Disney princess no more! Selena Gomez turns bad girl as she dons devil horns to celebrate 21st birthday with pal Lily Collins
Selena Gomez may be turning 21, but the former Disney star appeared reluctant to grow up as she put on a playful pair of devil horns and a feather boa to celebrate her birthday on Saturday night.
The actress teamed her sexy LBD that featured sheer polka dot print sleeves with a pair of killer black heels and the fancy-dress accessories for the occasion.
She was seen arriving at famous Hollywood hotspot the Roosevelt Hotel with best friend Lily Collins to start the celebrations.

The Come & Get It singer matched her vampy red lips to her fun headpiece and showed off the sleek tresses after getting her hair done earlier in the day.
While the brunette beauty doesn't actually turn 21 until Monday, she was eager to get in early and extend the festivities with her girlfriends.
British-American actress Lily rushed back from her appearance at Comic-Con on Friday, where she was promoting her new film, The Mortal Instruments: City Of Bones, to help her friend celebrate.

But while the 24-year-old made sure to be in attendance, some of Selena's other famous pals were notably absent.
Singer Taylor Swift was on the other side of the country, performing in Philadelphia on her Red Tour
- the 23-year-old's third world tour to date.

Also missing in action was Selena's on-off boyfriend, Justin Bieber.

The 19-year-old is reportedly trying to rekindle his relationship with his ex, though according to a source, Selena is 'disgusted' with his recent bad-boy behaviour.
An insider told Star magazine: 'Selena has told Justin that the speeding, turning up late [to concerts] and arguing with paps all have to end if they are going to work.'
It comes after the Never Say Never singer was filmed urinating in a mop bucket in a New York nightclub's kitchen and verbally insulting former president Bill Clinton.

Sources claim the stunning Spring Breakers star is a calming influence on her younger beau, but she won't stick around if his unpredictable antics continue.
Meanwhile, Selena has opened up to People magazine about her most recent moment of bliss - and it's not surprising that her answer wasn't Bieber-related.
'I'm a relatively new big sister, but it's the best thing ever,' she said of mum Mandy Teefey and step-dad Brian Teefey welcoming daughter Gracie Elliot into the world on June 13. 'My bliss is coming home and seeing her after I have been working.'
