She was the slightly precocious teenager who scored a hit single with her debut track Leave (Get Out).

But last night JoJo showed she is all grown up as she attended NYLON Magazine’s Young Hollywood Issue celebration ahead of her career comeback.

The 20-year-old singer was virtually unrecognisable as she posed on the red carpet wearing a tight denim cut-out dress which flattered her slim figure.

And with her hair dyed a more sultry black colour, JoJo proved she has left her child star days far behind her.

JoJo shot to fame when she appeared on the TV programme America’s Most Talented Kids at the tender age of 12.

Despite losing the talent contest, JoJo was quickly snapped up by a record label and started working on her debut record, which was released in 2004.

Following the success of her first single Leave (Get Out), JoJo continued to enjoy huge success with tracks including Too Little Too Late.

And now, after some time away from the music scene, JoJo is hoping to recreate her previous success with her new album Jumping Trains, due for release later this year.

Talking about the record, JoJo said: ‘My third album will be called Jumping Trains and it’s very symbolic for a variety of reasons.

‘Moving from Boston to L.A., transitioning from being a girl to being a young woman, living on my own, taking a different direction sonically, and just really finding myself and just jumping into a new chapter of life.’

JoJo has also been exploring the world of acting, with films under her belt including Aquamarine and RV: Runaway Vacation. She also made an appearance in the recently remade TV series Hawaii Five-0 earlier this year.

Other stars to attend last night’s NYLON event held at Bardot nightclub included socialite Paris Hilton, who wore a pretty turquoise dress, and actress Emma Roberts.

Peaches Geldof, meanwhile, attended the night out with ex-boyfriend Eli Roth, sparking more rumours the pair may have rekindled their relationship.

Despite the fact Peaches is in a relationship with singer Thomas Cohen, she and director Eli looked happy to pose together on the red carpet and even left together following the event.

Peaches tried out a new look at the party as well, opting to tie her hair into a bun and accessorise with a garland of huge flowers.

She teamed the new look with a black and white floral dress and a pair of black sandals.

Other stars to make an appearance included Glee stars Kevin McHale and Jenna Ushkowitz as well as Scream 4 actress Lucy Hale.

Singer Jordin Sparks, who recently posted a picture of herself showing off her bikini body on Twitter, displayed her newly-slim figure in a ruffled red dress which drew attention to her tiny waist.

Meanwhile, Hellcats star Alyson Michalka arrived at the event with her sister Amanda Michalka, who also appears in the hit US cheerleading programme alongside Ashley Tisdale.
