She might have been hoping for a night in the spotlight but Little Mix's Leigh-Anne Pinnock had to take a backseat to her bandmate on her birthday night out in London on Thursday.
While the brunette singer looked elegant as she stepped out for her 21st birthday, Jesy Nelson stole the show, turning up in a knockout gown.
The brunette star, who's slimmed down since appearing on the X Factor last year, decided to show off the fruit of her labours as she joined bandmates at the Madison Restaurant.
Wearing a floor length, sparkly black dress, with a low-cut neckline and a thigh-high split, Jesy showed off her enviable curves.
Wearing her hair sleeked back in a ponytail and with large, smokey eyes, the talent show winner showed off her transformation.
Looking like a star, Jesy breezed out of the restaurant, although she had to deal with a male flasher as she headed to her car.
Perrie Edwards decided to go for a more demure look, wearing a vintage-style floor-length gown paired with a sophisticated clutch.
While Jade Thirwall opted for a loose-fitting sequenced black dress, the birthday girl went all out.
Starting the night in a floor-length, lace ball gown, Leigh-Anne was the picture of sophistication, but as the night progressed the popstar clearly wanted to show off a bit more of her slim figure and donned a see-through beaded dress, showing off her black bra.
The pop starlet decided to invite a host of X Factor contestants past and present to her party, perhaps with the intention of imparting some wisdom on the newbies.
X Factor wild card hopefuls Times Red showed up to the bash, as did Jake Quickenden, who didn't make it through to live shows.
Last year's wild card Amelia Lily is clearly still friends with the girl group and left the party hand-in-hand with another of last year's finalists, Craig Colton.
Lauren Goodger, never one to miss a party, showed up to Leigh-Anne's bash at the restaurant in St Pauls.
Wearing an all black outfit, the reality queen was clearly going for a sophisticated look, pairing skin-tight black trousers with a long-sleeved black top, cliched in at the waist.
The TOWIE star must be trying to broaden her circle of friends as she took to Twitter to post a picture of herself with the birthday girl.
'Happy birthday LeighLittleMix x x', she wrote.
