The O2 Wireless Festival kicked off on Thursday with Jay-Z and Lily Allen taking to the stage, and the weekend saw Carl Barat, Fatboy Slim and the Counting Crows perform. We also spotted a few famous pairs in the audience, including Russell Brand and his new love Teresa Palmer, who had a busy Friday also attending the Silver Clef Awards. Pixie Geldof hung out with Alexa Chung and her Mulberry Bayswater — enter Fab UK's giveaway for a chance to bag one for yourself! Who do you think is more festival chic: Pixie or Alexa? Pixie was celebrating the end of school — it's easy to forget how young she is, isn't it? — and her Dad Bob took the youngest sibling on Saturday. Judging from the way she's styling out that bag, Tiger Lily looks set to follow in her fashion-savvy sisters' footsteps. What do you think of a pre-teen carrying an It-bag?
