Ariana Grande celebrated her 21st birthday at Disney World.
The 'Problem' hitmaker flew to the resort in Orlando, Florida with a small number of close friends and family members to enjoy a few days off before her special milestone birthday on Thursday (26.06.14).
The star, who grew up in Boca Raton near Miami, shared pictures of herself wearing Minnie Mouse ears, and posing next to Mickey Mouse, Prince Charming and several other Disney characters in front of Cinderella's castle on Twitter.
The brunette beauty was also presented with a massive four-tiered blue birthday cake, and she tweeted: "Spending my last few days as a non 21 year old in one of my favourite childhood places with my favourite people. Having the best birthday trip."
Shortly before arriving at the resort, she posted: "Birthday trip with a big group of friends & loved ones..... never been so excited."
The brunette beauty is also planning to have another huge party on Thursday and hinted she is very excited to continue her celebrations.
She tweeted today (25.06.14): "it's mah birfday tomorrow (sic)"
Ariana rekindled her relationship with ex-boyfriend Jai Brooks last month, following her split from British singer Nathan Sykes in December.
The singer previously insisted her break-up from the former The Wanted star was amicable.
She said: "I am so glad to have met him and have a friend like him in my life. He's an amazing person. It was very civil. It was mutual."

La Toya Jackson thinks Michael Jackson's life should be celebrated.
The 'Thriller' hitmaker's older sister, 58, paid tribute to him on the fifth anniversary of his death today (25.06.14), and urged the late music legend's fans "not to mourn" him.
In a statement to E! News, she said: "If Michael were here today he would tell us to all celebrate his life and not to mourn his death."
She also remembered the star, who is survived by his son Prince, 17, daughter Paris, 16, and 12-year-old son Blanket, as "the most incredible father, brother, son and the most talented performed this world has ever known."
She added: "Michael was all about love and peace and in honour of my brother I ask you to please do something kind for someone today, and, blast and dance to all the beautiful music he left us all.
"I will spend the day celebrating his life by listening to his music, looking through old home photos, watching his videos and concerts. Michael I love you forever and if you were today I know you would say, 'I love you more!' "
But Jermaine Jackson, 59, admitted it was still a "difficult day" for him on Twitter.
He tweeted: "However you are remembering Michael today, much love to you all on this difficult day #brother #father #uncle #son #artist #oneofakind
"Reading your messages. Your kindness and love are our comfort, too. Thank you."
A number of other celebrities also shared tributes to the late singer, who died of acute propofol and benzodiazepine intoxication at his Los Angeles home at the age of 50 in 2009, including Lady Gaga.
The 'Applause' hitmaker wrote on Twitter: "R I P Micheal. We love you. Today the world and media will grieve your absence, and think deeply of how we could have treated you better."

Justin Theroux insists he doesn't have cold feet about his upcoming wedding.
The 'Leftovers' star, who proposed to Jennifer Aniston on his birthday in August 2012, says they are still very happy together and can't wait to get married, but plan to keep their nuptials a secret.
Asked about their plans to tie the knot, the 42-year-old actor told 'Extra': "We have hot feet, but we're not going to let you guys know."
He added: "We're still happily engaged."
The couple, whose relationship was recently rumoured to be on the rocks, were all over each other at an after party to celebrate the premiere of Justin's new HBO series in New York City on Monday night (23.06.14).
A source previously said: "Justin and Jennifer were very lovey dovey. They were upstairs in a private VIP area all night with Liv Tyler and Jason Bateman.
"[They acted like] they were at their own private party. They didn't socialise much with other people."
The couple spent most of the event "upstairs," according to the source, who added: "Jen and Justin were very intimately talking for what seemed to be a long time. They looked very happy together."
Speculation recently began swirling that the former 'Friends' actress, 45, and her beau are planning to marry on Justin's birthday this year after undergoing "months of therapy" to work through their issues.

Lana Del Rey's boyfriend claims they haven't broken up.
The 'Young and Beautiful' hitmaker recently revealed she had called time on her long-time romance with Barrie James O'Neill, but he insists they're still together.
The Scottish rocker told gossip website TMZ.com on Tuesday night (24.06.14): "It's not over. It's not over. Don't believe what you read, it's not over. It's just stories, bedtime stories."
The Nightmare Boy star also revealed that he and Lana, 28, are also still working on new music together and praised her new album, 'Ultraviolence.'
He said: "We have done for a long time."
He added: "'Ultraviolence' is ultra good."
Lana claimed in an interview last week that she and Barrie, whom she first began dating in 2011, had split because she wanted to feel "free," but hinted they might get back together again.
She said: "We are currently not together. He is a wonderful person. But there are some things with which he has to deal. I will not explain it in detail. This was hard on our relationship, I no longer felt free. We'll see how it goes."
The on-again, off-again couple sparked rumours they'd got engaged last July when the brunette beauty was spotted sporting a diamond sparkler on her ring finger while house-hunting in Los Angeles.

Jennifer Lopez says dieting and working out are part of her job.
The 'Booty' hitmaker insists she has to work really hard to stay in tiptop shape, but believes it's her duty to look her best because she's a Hollywood star.
The 44-year-old beauty said: "You got to work out, you got to watch what you eat. It's a job - you've got to buckle down."
She added: "I'm not an exercise fanatic. I don't love it, but I do dance a lot for the shows, so that helps."
The singer - who has six-year-old twins, Emme and Max, with her third ex-husband Marc Anthony - recently lost 10 pounds by following a strict vegan diet and the Tracy Anderson Method, ahead of the release of her new album, 'A.K.A.'
She told Us Weekly magazine: "I feel great mentally and physically."
The newly single star, who recently called off her relationship with Casper Smart after two-and-a-half-years together, previously admitted she struggles to stay motivated in the gym.
Last month, she said: "I do have a healthy breakfast and try to fit in a workout when I can. I'm in fight mode right now because I have so many shows coming up, I'm trying to be healthy.
"It's so not easy. I hate it just like anybody else. It's not fun. You do it because you want to feel good and it does make you feel good after you do it."

Madonna's eldest child has enrolled in the star's alma-mater university.
The 'Hung Up' hitmaker's 17-year-old daughter, Lourdes Leon, whose father is personal trainer Carlos Leon, is set to attend the University of Michigan later this year, where she will pursue a bachelor's degree of fine arts in drama and theatre.
A source told UsMagazine.com that the teenager has registered in the Ann Arbor college's directory under her nickname Lola and will take undergraduate classes in a range of art forms and creative practices, from animation to traditional acting skills.
Her famous mother attended the same university in the 1970s, but dropped out before receiving her degree to pursue a career in music.
The 55-year-old star is clearly delighted Lourdes is following in her footsteps, as she posted a photograph of the university's merchandise store on Instagram on Tuesday (24.06.14), with the caption: "I think I'll stop in here! #unapologeticb***h (sic)"
The duo were first spotted taking a tour of the campus last November, and Madonna previously said: "I want my daughter to go to school there. I keep telling her, Ann Arbor is an awesome place."
Lourdes, who recently graduated from New York City's LaGuardia High School of Music & Art and Performing Arts, recently admitted she is nervous and excited about going to college.
Earlier this month, she wrote a blog post, saying: "I feel like high school graduation is something I've been talking about forever and now its finally here. I was so excited about 'being done with school' and now that I'm actually done I'm like clammy and sweating and nervous because... WHAT?!?! Knowing that I'm going to have to wake myself up for class, and not someone banging vigorously at my door for 5 full minutes, relieves me and worries me a little. Wrapping up High School has been pretty hectic (not actually doing THAT much so idk why) and words cannot express my excitement to sit in the sun and jam [with] friends (sic)."

Reese Witherspoon has put her Los Angeles home on the market for $14 million.
The 'Mud' actress and her talent agent husband, Jim Toth, are selling their lavish Spanish-style estate in Brentwood, California, which is comprised of three properties and is tucked away on a quiet cul-de-sac in a guard gated community.
The 38-year-old star, who has 21-month-old son Tennessee with Jim, bought the first property in December 2003 while still married to Ryan Phillippe, with whom she has a 14-year-old daughter, Ava, and a 10-year-old son, Deacon.
The Oscar-winning beauty picked up the second in 2009 following their divorce in 2007, and bought the final property on the same stretch of road in December 2013 for a combined total of approximately $11 million.
The Brentwood Circle home boasts unparalleled privacy, a pool, outdoor fireplace, sunken trampoline, playground, vegetable garden and sprawling landscaped gardens, according to real estate website Trulia.com.
It also features five-bedrooms, each with a private bathroom, a sweeping staircase, and a master suit with vaulted ceiling, fireplace, marble bath, two closets and a separate room for an easy to access office or gym.
Reese is hoping to sell the estate as a whole for $14 million or the main residence for $10.5 million. The adjacent 28,870 square foot property, which includes four bedrooms and four bathrooms and was previously described as a "warm and inviting... enchanted cottage" - is also available to be purchased separately for $3.5 million.
A source told Variety.com that Reese and her family want to move to the Pacific Palisades.
The actress finally sold her ranch in Ojai, California, where she and Jim tied the knot in 2011, for $4.98 million earlier this year, after originally placing it on the market for $10 million.

Melissa McCarthy used to cry over her weight when she was a young actress.
The 'Bridesmaids' star admits she cries easily but was often upset about her looks and thought she needed to be skinnier to be successful in the film industry.
She told People magazine: "In my 20s I used to cry about why I wasn't thinner or prettier, but I want to add that I also used to cry about things like, 'I wish my hair would grow faster. I wish I had different shoes ...,' I was an idiot ... It's a decade of tears."
These days, the 43-year-old actress - who is married to her 'Tammy' co-writer Ben Falcone - doesn't care about looking silly and admires people who don't care about the opinion of others.
Melissa said: "I'll do almost anything for a laugh. I'm completely delighted by people who think, 'I don't care what anybody else thinks, I look great in this, and I rock it and I love it.' It's such a delightful sort of confidence."
The actress has never felt the need to change how she looks but is annoyed by horrible comments about her weight and her acting skills.
She said: "I've always thought, 'If you want somebody different, pick somebody else.' But sure, criticism can sometimes still get to me. Some things are so malicious, they knock the wind out of you."
The brunette star was described as "America's plus-size sweetheart" in a recent article and Melissa thinks it was unfair to mention her weight.
She said: "It's like I'm managing to achieve all this success in spite of my affliction ... Would you ever put that in the headline for a male star?"
As a mother to daughters Vivian, seven, and Georgette, four, she wants them to care more about laughter and memories than looks as they grow up and she's grateful for what she has in terms of her family and success.
She said: "Ben and I will have moments where we look at each other and go, 'This is not bad at all'. I feel like I got hit with a lucky stick."

Shakira doesn't want to marry her long term boyfriend Gerard Pique.
The 'Hips Don't Lie' singer - who has a 17-month-old son, Milan, with the Spanish soccer star - insists she isn't keen on tying the knot with Gerard, 27, as it won't make any difference to their relationship.
She told Glam Belleza Latina: "We already have what's essential, you know? We have a union, a love for each other, and a baby. I think that those aspects of our relationship are already established, and marriage is not going to change them."
However, the blonde beauty insists she wouldn't rule out marrying the Barcelona defender altogether.
She added: "But if I'm ever going to get married, he's the one."
The Grammy Award-winner - who released her tenth studio album 'Shakira' in March this year and finished her judging role on season 6 of 'The Voice US' in May - is currently enjoying spending time with her baby son.
When asked what makes her happy, the 37-year-old star said: "I suppose it's knowing that I can share with Milan everything I've learned and seen. I don't have to keep all of that information to myself. I love teaching him something new every day."

Adam Levine had the "time of his life" when he first found fame.
The Maroon 5 singer moved into Los Angeles' Chateau Marmont hotel after the release of debut album 'Songs About Jane' in 2002 and admits the subsequent hedonistic period - which saw him romantically linked to a string of women including Paris Hilton, Lindsay Lohan and Jessica Simpson - was "amazing".
He said: "All of a sudden, I had money in my bank account. I hadn't had a break in a long time. And I went a little f**king nuts. You know? And good. I deserved to go a little bit nuts. And I had the time of my life.
"Men are not as sophisticated as women. They're not as mature as women. They're not as connected with their emotions as women. There's a very Neanderthal quality that still exists in a lot of men. There's the carnal s**t you can't deny.
"And if you're in the public eye, to me, it's very boring to say what you have to say and be media trained to the extent that you don't ever reveal any truth. There was a time in my life when I lived probably a bit more on the primal level. And it was amazing."
However, the 35-year-old singer - who is engaged to Victoria's Secret model Behati Prinsloo - admits his past antics have tainted his reputation even now.
He added in an interview with America's GQ magazine: "That was kind of the foundation of all the negative s**t I still get.
"I was out there having fun, you know. I didn't give a s**t, and I got burned for it. People change; people grow up, get more self-aware and in tune with all this s**t."

Channing Tatum and wife Jenna Dewan-Tatum were left "mortified" when they went for a couples massage.
The 'Witches of East End' actress wanted to treat her husband at a spa in Canada, but the pair were horrified when they discovered they would have to be "butt naked".
Speaking on 'Chelsea Lately', she said: "In Vancouver, there's an Indian spa -- and they don't tell you this -- they take you in there and they put you in a sari and then they take it off, so you're completely butt naked.
"You're normally naked but it's [usually] like dark lighting. First of all, there were really beautiful Indian women, so already I was like, 'Maybe I'm regretting this.'
"And then I'm watching Chan be mortified -- this is the funniest part --because I'm sitting there in the steam so I go first and I'm like, 'Oh, he has no idea.'
"Like, she saw him just sitting there naked and then they bring him out and he's just completely naked, and she completely knows who he is, obviously.
"He looks at me like, 'I am going to kill you.' It was quite mortifying for both of us."
Jenna - who has 12-month-old daughter Everly with her spouse - recently admitted the '22 Jump Street' actor doesn't like her filming sex scenes.
Asked if it was true her spouse "doesn't like her having sex scenes with other men" on TV, she said: "So true."
She added: "It'd be weird if he was like, 'Ah, I'm cool with it, do whatever,' you know?
"It's never fun [shooting love scenes], but you just get really used to it, it's weird."
