Rita Ora and her ''wifey'' Cara Delevingne partied together at the O2 War Child BRIT Awards Concert with Muse on Monday night (18.02.13).
The 22-year-old singer and the 20-year-old model watched the band perform to just 2,000 fans at the O2 Shepherd's Bush Empire in London and as well as rocking out they also took the opportunity to chat and mingle with the other stars in attendance.
Rita and Cara were seen backstage talking with Harry Styles and at one point the 'Hot Right Now' hitmaker seemed to openly flirt with the One Direction heartthrob - who is rumoured to have briefly dated Cara in the past.
The virtually inseparable pair sipped on cocktails throughout the evening and Rita was also seen laughing with Muse frontman Matt Bellamy's partner Kate Hudson as they watched the gig in the VIP seating area.
After the concert - the fifth year of War Child and O2's annual BRIT Awards Concert - Rita and Cara made their way to the Dazed and Confused with Belvedere Vodka bash at Cafe Royal and partied late into the night.
Rita showed off her sexy figure in a red cropped top which bared her midriff paired with checked trousers and a long matching checked coat, while Cara was bang on trend in loose grey trousers, a blue silk jacket and a pair of silver high-tops.
'How We Do' hitmaker Rita recently revealed she and best pal Cara call each other ''wifey'' and have both sworn off men to spend time with each other instead.
She said: ''I have no time for the opposite sex at the moment. Strictly none. I've only got a wifey! She's officially mine. She's, like, untouchable. I've taken her off the market. You know what a wifey means? It's like your other half. Like when you get married, like, that's your wife!''
Earlier in the day, Rita supported her ''wifey'' at the Burberry Prorsum runway show, before performing an acoustic set at the Calvin Klein store launch. Both events were part of London Fashion Week.
