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.

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.
