Selena Gomez says acting helps her "escape from the madness" in her life.
The 'Rudderless' star, who sought treatment in rehab earlier this year and recently split from Justin Bieber again, prefers to take on roles that help her to grow as a person and always insists on auditioning, as she wants to earn her success.
The 22-year-old beauty told UsMagazine.com: "Honestly, the reason why I take certain parts is not because I feel like I could just accept it. I want to be the person who earns it. I've auditioned for every movie I've been a part of, and I've wanted to genuinely feel like I earned it."
The 'Spring Breakers' star is often "uncomfortable" on set, but thinks it's a good thing.
She explained: "That makes me a better actress. Even though I feel like it can be uncomfortable sometimes, that's honestly what's going to make me grow.
"I'm extremely lucky. I could be doing certain films that I'm comfortable [doing]. I love to push myself. I can't say I got this [role] because of who I am. I got this in spite of who I am. That's what I love about acting. I can escape from the madness. This project ['Rudderless'] in particular made me feel like I get to be a real actress."
She added: "I would rather be in a smaller part and learn from people like Bill [William H. Macy], Felicity [Huffman], and Billy [Crudup].
"One of my best friends always told me, 'If you're the smartest person in the room, you're in the wrong room.' "

Amanda Bynes' father allegedly thinks she would benefit from "a long stint in jail."
The 28-year-old star's mother, Lynn Bynes, is eager to fly to New York City to "save" her again after she was arrested last week for driving under the influence (DUI), but her husband, Rick Bynes, reportedly doesn't think there is anything else they can do to help the troubled actress, who was allegedly caught trying to steal a $200 hat at Barneys in Manhattan today (08.10.14).
A source told gossip website RadarOnline.com: "Lynn had been making plans to go to New York City because she had been growing so concerned about Amanda's bizarre behaviour.
"Rick was opposed to the visit and thought it would be a waste of Lynn's time and their money because there is nothing she can do to help Amanda. Amanda would likely refuse to see her anyway -- and that would be if Lynn could even find her.
"[Lynn] is really torn between taking her husband's advice and saving Amanda. It's an impossible situation for Lynn."
The insider added: "Her parents are surprised that she hasn't been arrested in New York City yet ... though Rick thinks a long stint in jail would be the best thing for Amanda."
Meanwhile, the 'Easy A' actress, who was placed under her mother's care via a conservatorship after she was involuntarily hospitalised last year following months of erratic behaviour, reportedly "acted crazy" when she was accused of stealing at Barneys, but security let her go after she claimed she didn't mean to take the hat out of the store and was merely trying to escape being chased by fans, according to gossip website TMZ.com.
The upmarket department store made her sign a no-trespass agreement, banning her from entering the shop ever again.

Mariah Carey wants Nas to set her up on a date.
The '#Beautiful' hitmaker, whose estranged husband Nick Cannon recently confirmed they have been separated for several months, is reportedly eager to start dating again and wants her close friend to play matchmaker.
A source told Us Weekly magazine: "[She] texted Nas, wondering if he had any friends she could go out with -- or even just hook up with. But Nas is nervous to introduce her to anyone."
The star has been friends with the 'Nasty' rapper for more than a decade and they recently collaborated on the song 'Dedicated' for the 44-year-old singer's latest album, 'Me. I am Mariah... The Elusive Chanteuse'.
Meanwhile, 'America's Got Talent' host Nick has formed a close bond with Mariah's former manager Randy Jackson.
The 34-year-old star was spotted having dinner with the former 'American Idol' judge and an unidentified blonde woman at Matsuhisa in Beverly Hills late last month.
Nick, who has three-year-old twins Monroe and Moroccan with Mariah, stayed behind to chat with the mystery woman afterwards.
An eyewitness said: "After Randy left, [they] kept chatting and laughing. Nick had a big smile on his face."

Kanye West and Kim Kardashian West's wedding pastor believes in their marriage.
Rich Wilkerson Jr., who officiated the couple's lavish wedding in Florence, Italy last May, has no doubt they will spend the rest of their lives together.
Speaking about their wedding, he told PEOPLE.com: "I got to give my message. They wanted a Christian wedding, and wanted me to talk about Jesus. It wasn't a message of hate and judgment; it was a message of hope and love. Kim and Kanye have both told me that they're followers of Jesus; we're on the journey together as friends. I believe in them, and I believe in their marriage."
The 30-year-old pastor, who is set to star in his own new reality TV series, 'The Wilkersons,' with his wife Dawn on the Oxygen network, admits his friendship with Kim, 33, and Kanye has completely changed his life.
He said: "I never expected that anyone would care who performed the ceremony. Celebrities get married all the time and no one knows who their pastor is. I didn't tell anyone I was doing the wedding; I just went to Italy and did it. And then everything started moving really fast."
Rick became friends with the 'New Slaves' rapper, 37, after being introduced by a mutual friend in Miami two years ago, but admits he doesn't always agree with the outspoken star's infamous rants.
He said: "I don't have to agree with everything that someone does to love them
"I tell the truth if I'm asked, and we may disagree, but we're still friends. Kanye knows what my standards are. There's a respect there.

Selena Gomez dumped Justin Bieber after he had dinner with Kendall Jenner.
The 'Come & Get It' singer, who has had an on-again, off-again relationship with the Canadian star since 2010, was reportedly furious when she discovered her boyfriend, 20, met up with the model in Paris while she was sightseeing after they flew to the city to attend a number of fashion shows together last week.
A source told In Touch Weekly magazine: "Selena was absolutely livid when she found out Justin had dinner with Kendall. He lied to her about it. She was so angry that she changed her flight to come back to LA two days early and told him their relationship was over - again."
The 22-year-old actress' friendship with Kendall, 18, and her sister Kylie Jenner, 17, fizzled out after she found text messages from Kylie on Justin's phone after they attended the Coachella Valley Music & Arts Festival together in April.
The insider added: "She told Justin she wanted to have nothing to do with them. That meant he had to cut them off, too.
"It turns out Justin has been texting Kendall the whole time and Paris wasn't the first time they secretly had dinner together.
"Justin admitted it and insists they're just friends, but Selena doesn't believe him, and they had a screaming match over it. She feels completely humiliated."
Another source told Us Weekly magazine that Selena "doesn't trust Kendall's motives."
Justin and Kendall were spotted dining at Ferdi in Paris shortly before attending the CR Fashion Book party with her mother, Kris Jenner, and sister Kim Kardashian West.
Selena also attended the party with other friends.
The following day she flew back to Los Angeles with Kris, 58, but hinted she wasn't happy about the situation on Twitter, writing: "Random, long flight. So happy to be home."

Sofia Vergara is thinking about undergoing hypnosis to cure her sweet tooth.
The 'Modern Family' actress admits she only works out so she can eat cake on a regular basis and claims she is seriously considering going to a specialist to help her get over her obsession with candy.
The 42-year-old star told the November issue of Shape magazine: "I heard about someone in L.A. who got hypnotised so they wouldn't eat candy. I'm seriously looking into that because I'm obsessed."
The brunette beauty, who is dating 'Magic Mike' star Joe Manganiello, "has always been very happy" with her figure, but credits her co-star Julie Bowen for inspiring her to get fit and healthy two years ago.
She said: "I hit 40 and I started seeing a softness everywhere on my body ... I knew it was time to do something, so I did.
"Being around Julie and seeing how motivated she is ... I started to think more about it."
She added: "When I do indulge, I exercise a bit harder the next day. My workout motto is really simple: No pain, no cake!"
Sofia is unable to run or do traditional squats because of her "bad knees" so she trains with a Pilates-like machine called the Megaformer.
She added: "I don't love it at all, but I love how my body's changing.
"My body is looking better than it used to, but I wish I had worked out more when I was younger and taken it as seriously as I do now. My niece is 21 and she loves exercising, and I tell her, 'Keep doing it so you don't have to go crazy with it when you're my age!' "

Jennifer Garner claims she will always have a "baby bump."
The 'Alexander and the Terrible, Horrible, No Good, Very Bad Day' star, who has three children, Violet, nine, and Seraphina, five, and Samuel, two, with husband Ben Affleck, doesn't think her stomach will ever be completely flat again and claims people still congratulate her because they think she is pregnant.
The 42-year-old actress told 'The Ellen DeGeneres Show': "I get congratulated all the time by people that I know! [They say] 'I hear you're pregnant, oh my god!' This one woman who had babysat for us said, 'Oh my gosh, I can't wait for number four' and I thought, 'What is going on?'
"I asked around, and apparently I have a baby bump. I'm here to tell you that I do. I do have a baby bump. I am not pregnant, but I have had three kids and there is a bump."
She added: "From now on ladies, I will have a bump, and it will be my baby bump. Let's just all settle in and get used to it. It's not going anywhere! I have a bump, it's name is Violet, Sam, Sera."
Jennifer recently admitted she gained a few pounds while Ben was bulking up to portray Batman in 'Batman v Superman: Dawn of Justice'.
She said: "There's something about it... whenever one of us has to be really good, the other one pudges up. I don't know why it is, but I blame my pudginess on his strict and disciplined place in life. There's something about it that just makes me like, 'Well, I'm gonna have a bonbon. I'm gonna have some ice cream.' "

Demi Moore has banned her children from having cosmetic surgery.
The 51-year-old actress, who has three daughters, Rumer, 26, Scout, 23, and Tallulah, 20, with ex-husband Bruce Willis, is reportedly terrified they will resort to extreme measures in a bid to look perfect all the time.
A source told the National Enquirer magazine: "Demi thinks all her daughters are naturally beautiful.
"She's worried that Rumer and her sisters feel pressure to chase an unrealistic Hollywood physical ideal."
The 'LOL' star, who is rumoured to have had multiple plastic surgery procedures in the past, is said to be doing everything she can to ensure her girls don't do anything drastic to change their appearances.
The source said: "[She] got a few of her daughter's friends together and lectured them about the pitfalls of cosmetic surgery."
Demi has rarely been away from Tallulah's side since she was released from rehab last month.
The blogger sought treatment shortly after admitting she struggled with an eating disorder and body dysmorphia when she was younger.
During an interview in August, she said: "I struggled a lot when I was younger.
"Like I'm diagnosed with body dysmorphia with reading those stupid f***ing tabloids when I was like 13 and feeling like I was ugly, like always. I believed the strangers more than the people who loved me because why would the people who love me be honest?"

Taylor Swift insists the idea of going on another date gives her a "partial panic attack".
The 24-year-old star - who has been unlucky in love with several stars including Harry Styles, Jake Gyllenhaal, John Mayer and Joe Jonas - admits it would take an "astonishing human being" for her to even think about dating again because she is content with her life at the moment.
She said: "I'm not going to compromise the happiness and independence that I've found for just anybody. The idea of a date gives me a partial panic attack!
"It would take an astonishing human for me to even consider getting back into a relationship. It would take something really, really, really, really different - a kind of a one-in-a-million person for me to face all that.
"I don't have any kid of idea who I'd want to be with, because I don't have any pieces missing from my life right now. I'm not looking for anything to complete. I think that's a nice place to be."
The 'I Knew You Were Trouble' hitmaker insists she is quite happy spending time at home with her two cats - Meredith Grey and Olivia Benson - and is admits her upcoming fifth studio album '1989' isn't a break-up album because she hasn't been left "devastated" by a guy in the last two years.
Speaking to PEOPLE magazine, she added: "When I'm deeply hurt, I usually respond by writing exactly how I feel in a song, but I just haven't been devastated in the last couple of years.
"I made the decision to spend time on my own and figure out who I am.
"Emotionally speaking, '1989' is not a heartbreak record. My music is derived from what's happening in my personal life, and I haven't had my heart broke."

Jason Biggs wishes he could have lesbian sex on 'Orange is the New Black'.
The 36-year-old actor - who plays Larry Bloom in the comedy/drama series - has joked he would like his character to get more involved in the "craziness" in the prison drama, despite admitting he loves starring opposite Taylor Schilling, who plays his on-screen partner Piper Chapman.
During an appearance on chat show 'Conan' alongside his female co-stars Uzo Aduba and Taylor, he said: "I have prison envy. I'm not going to lie, I do. I will say this, I will say like these ladies have the ... I mean really seem to have the best time.
"I have the best partner in the world with Taylor Schilling. Most of my scenes are just with her. But I wish I could get to be in on the prison fun and craziness and lesbian sex."
While the star - who has seven-month-old son Sid with wife Jenny Mollen - insists he wants to play a crazier role in the show, he recently admitted enjoying portraying a mature character in 'Orange is the New Black' after becoming known for portraying awkward Jim Levenstein in the 'American Pie' film franchise.
Speaking about his part in the prison drama, he added: "It is different, I don't know whether I have a preference in general but for now, at this point in my life, it is preferable.
"I love that goofy comedy and I want to do more of it but for me right now I feel I personally grew up and for a while the roles I was doing haven't quite grown up with me and this is the first one where I feel like it has."
UK viewers can watch the cast of 'Orange is the New Black' being interviewed on Conan at 11pm tonight (08.10.14), on truTV (freeview channel 68) - the home of larger than life characters in real situations.

A phone conversation allegedly between Hank Baskett and the transsexual model he has been accused of having an affair with has appeared online.
In the recording, which is dated May 29 and has been obtained by RadarOnline.com, a male voice answering to the name Hank can be heard begging Ava Sabrina London not to share the details of them having sex a month before.
The man can be heard saying: "I just wanted to confirm that you hadn't said anything.
"They just said two weeks before Kendra was pregnant that I hooked up ... I hate to say it 'cause I would never say this word, but they said I hooked up with a tranny."
The model reassured the caller, saying "I didn't say nothing," and goes on to claim she had turned down several offers for her story.
The man replies: "Thank you so much, thank you. Thank you so much.
"You're making me feel so much better right now because you said you didn't say anything."
Hank has repeatedly insisted to wife Kendra Wilkinson - the mother of his children Hank Jr., four, and four-month-old Elijah - that the infidelity claims are false, but the 'Kendra On Top' star has admitted she feels "some of it is true".
However, the blonde beauty has said she won't be calling time on their marriage just yet.
She said recently: "In my eyes, life is too short and this man who I loved for six years - I believe he deserves... a second chance, if he did make a mistake.
"And right now I'm working that out. I'm working on what happened and if this was a mistake, which I believe, I'm starting to believe it was.
"If I believe that Hank had an affair on me, the divorce would have gone through already. I'm holding on to any hope I have."

Jennifer Lawrence would rather date someone "boring" than have "passion" in her relationships.
The 'Hunger Games' actress - who is romancing Coldplay frontman Chris Martin - says her ideal man is someone willing to stay home and watch her favourite reality TV shows with her.
She said: "Isn't boring so much better than passion?
"[I like to date] somebody [who] has the same taste in reality TV. 'Shark Tank'. Wait! Oh, 'Dance Moms' -- that is a good one! OK, maybe my favorite isDance Moms but I do love my 'Real Housewives'. But there's also -- there's 'Doomsday Preppers'. 'Hoarders' is OK. I find it gets a little boring after a while, but it's great.
"I love 'Intervention', New York 'Housewives' -- and Beverly Hills, New Jersey, and Atlanta 'Housewives'. I mean, I love them all, but Miami -- oh, my God! Miami is really special."
"Basically, what I'm saying is all I need in a relationship is somebody to watch TV with me."
The 24-year-old beauty - who previously dated actor Nicholas Hoult - also confessed to liking a man who "isn't afraid to fart in front" of her and despising arguments.
She told Vanity Fair magazine: "I'd rather have just a peaceful time. [Those] are deeper because you can be your true self with somebody, and somebody can be their true self with you.
"I don't like fighting, and I find argumentative people the most annoying people on the planet. Like, why do you still want to be fighting? It's just unattractive."
