Demi Lovato doesn't have a "type" when it comes to dating.
The 21-year-old singer - who has been romantically linked to Wilmer Valderrama in the past - insists she doesn't fall for someone based on their looks or nationality because she thinks the most important thing is their personality.
Speaking in the new issue of Cosmopolitan for Latinas magazine, she said: "I have [dated Latinos], but it's not important to me--I don't have a nationality preference. I don't really have a type.
"I don't think that you fall in love with someone for their clothes or their style. For me, it's about the person."
Meanwhile, the 'Heart Attack' hitmaker admits she's not keen on singing about the sexy side of her relationships in her songs because she doesn't want her relatives to hear.
She explained: "Sex is a part of life and it's a personal decision. Some people put it in their music, which is awesome and good for them.
"But for me, there's still that weird feeling in the back of my head that's like, 'All right, I know that my mom and dad are going to hear it and my little sister, and that's really weird for me.' But if I feel like expressing myself in that kind of way, then I'll be like, 'All right, guys--look the other way!'"

Jennifer Lopez "went through a tremendous low" after her split from Marc Anthony.
The 44-year-old singer - who has six-year-old twins Max and Emme with her ex-husband - admits she struggled to come to terms with their break up in July 2011, but she believes the heartbreak made her a stronger person.
Speaking to PEOPLE.com, she said: "I went through a tremendous low but I wouldn't change anything [about my past] because it made me who I am."
The 'On The Floor' hitmaker, who tied the knot with Marc in 2004 after two previous failed marriages, insists the split allowed her to "take a look at what was going on" in her life and re-evaluate her past relationships.
She explained: "As women we can sometimes give ourselves away. I was certainly guilty of that for some time. Now I realise I am good on my own, so now I can share my life with somebody."
However, Jennifer, who has been dating backing-dancer Casper Smart for the past two years, believes her children have allowed her to understand the real meaning of love.
She said: "I just feel like I went through a real growth spurt as a human being [when I became a mother].
"Having my babies allowed me to realise what real unconditional love was."

Kristin Cavallari has given birth to a baby boy.
The former 'The Hills' star and her husband Jay Cutler, who already have 19-month-old son Camden, welcomed their second child Jaxon into the world today (07.05.14).
The 27-year-old shoe designer took to her Instagram this evening to announce the arrival of her new bundle of joy, who weighed a healthy 7lbs 11oz, along with a picture of some cute booties, a baby hat and her hospital band.
She wrote: "Jaxon Wyatt Cutler 7lbs 11oz 5/7/14 (sic)".❤️
The blonde beauty announced she and her beau, whom she married last year, were expecting another baby together back in October 2013, before revealing the tiny tot's sex in February.
Kristin previously claimed she wasn't nervous about the birth and couldn't wait to meet her baby son.
She said earlier this year: "The first time [you have a baby], you're anxious, you're nervous, you're excited, you have so many emotions. It's like the closer you get to your due date, you're ready but you're also not quite ready, so you don't mind if the baby stays in there. But this one, I'm like, 'Let's get him out here, I want to see him, I just want to hold him and see what he looks like'."
However, Kristin was feeling anxious about how Camden would react to their new arrival.
She said: "I don't want him to feel like he's being replaced. I know the first few months are going to be hard when I'm breastfeeding all the time. We're just going to try to be so careful to make sure he's still getting a lot of attention, knows he's still extremely loved and this baby is in no way taking his spot."

Angelina Jolie didn't think she'd ever have children.
The 38-year-old actress has six kids, Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and twins Vivienne and Knox, five, with her fiancé Brad Pitt, but she admits she ruled out having a family of her own when she was younger because she thought it was just a fantasy.
Speaking in the June issue of ELLE magazine, she said: "I never thought I'd have children, I never thought I'd be in love, I never thought I'd meet the right person.
"Having come from a broken home--you kind of accept that certain things feel like a fairy tale, and you just don't look for them."
The 'Unbroken' director has been dating Brad, 50, whom she met on the set of 'Mr & Mrs Smith', since April 2005 and she believes they've grown stronger as a couple as the years have gone on.
She explained: "You get together and you're two individuals and you feel inspired by each other, you challenge each other, you complement each other, drive each other beautifully crazy.
"After all these years, we have history, and when you have history with somebody, you're friends in such a very real, deep way that there's such a comfort, and an ease, and a deep love that comes from having been through quite a lot together."

Scarlett Johansson is glad she found fame 10 years ago.
The 29-year-old actress - who shot into the limelight after starring in 'Lost in Translation' in 2003 - doesn't think she would have been able to cope with her celebrity status if she had been a teenager now.
She explained to USA Today: "When I was first becoming more publicly recognisable, I was probably about 18 or 19 and that was 10 years ago - I look at kids that are 18 or 19 now and coming into the spotlight, that would be excruciating. I feel very fortunate that I was able to have a bit of a smoother transition into my young adulthood without having people videotaping me."
The blonde beauty - who is expecting her first child with her fiancé Romain Dauriac - insists she'll never join any social networking sites because she doesn't want to be criticised for everything she posts online.
She said: "It seems much more complicated now. If you're constantly feeling like you're being hunted, that's going to drive you nuts. You have to be wise about the choices you make."

Neil Patrick Harris thinks coming out as gay has improved his career.
The 'How I Met Your Mother' star believes he's received more work opportunities since revealing his sexuality in 2006 because bosses are more inclined to hire people that openly express their personality for all to see.
Speaking in the upcoming issue of Rolling Stone magazine, he explained: "Once all the cards were on the table, I got more opportunities than ever. Some actors don't get hired because you can't look into their soul and see what they're like, because they're kept guarded."
The 40-year-old star - who has three-year-old twins Gideon and Harper with his fiancé David Burtka - realised he had "crushes on boys" when he was a youngster but he didn't know "how that would be manifested" as he got older.
He said: "I think it would be easier to make that leap at that age now, because there are so many examples but not back then, in a tiny town in the middle of the mountains of New Mexico."
Although, Neil insists he wasn't bothered by his attraction to the same sex when he was younger, but he just didn't know how to pursue it at the time.
He added: "I wasn't troubled by it. Playing footsie with a friend under the table at school was very charged, to me, but I didn't know then what to do about it."

Katie Price is "appalled" her husband Kieran Hayler has allegedly had an affair with her best friend.
The former glamour model, who is pregnant with her fifth child, has defended her decision to announce the end of her third marriage on her Twitter account today (07.05.14) and claims the tweets were "a sign of" her broken heart.
She wrote on her official website tonight: "I appreciate most people will have seen my tweets on the subject of my marriage to Kieran.
"I make no apologies for them though it will be appreciated that, sending them immediately after Kieran confirmed to me what he had been doing for the last 7 months, those tweets were a sign of my heart breaking.
"That he was doing it with a close friend of nearly 20 years is hard to understand.
"This statement however is from my head, not my heart. I am appalled that someone I loved, trusted and believed in has behaved in this way. If he had so little respect for our relationship I would have hoped he would have thought about our child or the one that we have on the way. That he did not means he will no longer be part of my life. I will do all I can to ensure he maintains a relationship with his children should he want that."
Katie, 35 - who has children Harvey, 11, Junior, eight, and Princess, six, from previous relationships, as well as eight-month-old Jett with Kieran - branded the builder "disgusting" after finding out about his alleged affair.
The reality TV star - who has only just discovered she is six months pregnant - married Kieran in January 2013, just a few months after they started dating.

Bruce Willis has become a father again.
The 'Die Hard' star and his wife Emma, 35, welcomed their second daughter Evelyn Penn Willis into the world on Monday (05.05.14) in Los Angeles.
The tiny tot weighed a healthy 8lbs 10oz and is said to be doing "beautifully" following her delivery, a representative for the couple told Us Magazine.
Bruce and Emma also have two-year-old daughter Mabel together and were over the moon when they discovered last year they were expecting another child.
The couple - who got married five years ago - announced their baby news in December after the model was spotted showing off her bump at a farmer's market in Los Angeles.
Meanwhile, the 59-year-old actor also has three daughters, Rumer, 25, Scout, 22, and Tallulah, 20, with his ex-wife, Demi Moore, and a friend claimed last year that Bruce wouldn't mind having another baby girl to add to his brood.
The insider said: "[Bruce is] adorable with Mabel and all of his girls. It's hilarious to see the tough guy stereotype just melt away. He'll put on a baby voice, get cute with her. Being a dad is no doubt the most important thing for him."

Lily Allen bonded with Kanye West over their albums at the Met Ball.
The 'Hard Out Here' singer, who named her latest album 'Sheezus', a play on the rapper's 'Yeezus' record, insists it was "quite funny" when they met at the bash which took place on Monday (05.05.14) in New York.
Talking on British chat show 'Loose Women', she said: "It was quite funny because my album is called 'Sheezus' and his is called 'Yeezus' so it's 'Sheezus' and 'Yeezus'."
The brunette beauty didn't actually glimpse at Kanye's fiancee Kim Kardashian's famous butt and insists she couldn't say whether 'Keeping Up With the Kardashians' star's curves are as big as they look in pictures.
Asked about whether Kim's bottom is that massive, she answered: "I have to say I wasn't looking. I was looking at her face. We were talking so it would have been weird if I was looking."
Although Lily is thrilled to be invited to high-profile events like the Met Ball she insists they aren't "fun" and she would rather spend time with her friends.
She said: "It's really lovely to be invited to those things. It's not a night out with your friends, it's not fun, everyone is like lets pose for the camera and is a little bit stiff."

Emma Roberts looked like she "rolled in mud" when she had a spray tan.
The 23-year-old actress admits other teenagers used to mock her pale skin, but her attempts to get a golden glow when she attended her friends prom ended in disaster.
She recalled: "I was that person who went with the boyfriend's friend.
"I had a really bad spray tan, because I used to get made fun of for being pale. I thought, 'I'm gonna get a spray tan and be really glamorous', but I looked like I rolled in mud.
"So, um, that was really fun."
The 'Palo Alto' actress was educated at home so admitted she didn't have a "regular" school experience.
Speaking to James Franco for V magazine, she said: "I was home schooled, which was definitely not like a regular high school experience."
Emma - whose aunt is Hollywood beauty Julia Roberts - recently admitted her parents didn't want her to pursue an acting career.
She said: "She [my mum] just didn't want me to go into it [acting] young. When you come from a family that's in the industry, they're always like, 'Be a doctor! Be a lawyer!' But we end up wanting to be actors."
When asked if she received any advice from Julia, she added: "No one said anything to me about acting because they hoped it would just be a phase. But I kept doing it!"

Yvonne Strahovski has to get her hair cut every three weeks for her role in '24: Live Another Day'.
The blonde beauty portrays new character CIA field operative Kate Morgan who is handed the task of apprehending fugitive former Counter Terrorism Agent Jack Bauer - played by Kiefer Sutherland - in the action drama.
Yvonne has revealed the show's unique 24-hour, real time format presents unique problems, such as maintaining the same style and appearance so each episode is consistent.
Speaking at a screening of the first of episode of the series at Old Billingsgate Market in London on Tuesday night (06.05.14), she said: "(During shooting) don't put on weight because it's really bad for the show and we're all cutting our hair every three weeks or four weeks. We have to otherwise it would grow and then it doesn't match."
The series has been off air for four years since Season Eight aired in 2010 and lead actor Kiefer, 47, admits he was pleased to get four months notice to get in shape for the show's numerous action scenes and daredevil stunts.
The actor - who joined Yvonne, Mary Lynn Rajskub and several other castmates at the screening and Q&A - said: "The show is really physical and my experience with '24' is that it's not a question of if you get injured, it's a question of when and how severely. So the better shape that you're in, the better chance you have of getting through a shoot without getting into real trouble. I was lucky that I had four months to prepare for this, I wasn't doing another show."
The cast are still shooting the final instalments of '24: Live Another Day' in London, and the series starts tonight (07.05.14) at 9pm on Sky 1 HD and Sky 1 +1.

John Mayer "was aware" he was buying fake Rolex watches, court documents have claimed.
The 'Gravity' hitmaker filed a lawsuit against Robert Maron in March for allegedly selling him timepieces he knew to be fakes, but the dealer has requested the suit be dismissed and he be awarded damages, on the grounds the singer knew the "risks" involved with his purchases.
Documents filed by Maron's lawyers and obtained by RadarOnline.com read: "[Mayer] was aware of the facts of which he now complains, yet elected to proceed in light of the known risks, which Plaintiff knowingly and volitionally assumed.
[Mayer] acknowledged, ratified, consented to, and acquiesced in the alleged acts ... of Defendants."
In his documents, Maron insists he "substantially performed the terms and conditions required under any and all contracts" with the 36-year-old star and when he complained the watches turned out not to be genuine, he "failed to mitigate or attempt to mitigate damages" before filing the lawsuit.
As well as requesting the suit be dismissed, the watch dealer - who is Charlie Sheen's best friend - is asking to be awarded attorneys' fees, plus an additional amount to be determined by the court.
Rolex is one of the world's most prestigious watch brands, with the coveted timepieces ranging anywhere from $5,000 with the most exclusive designs costing upwards of $500,000.
