Kate Moss, Lily Allen and Samantha Morton led a star-studded rendition of Happy Birthday at British festival Glastonbury - to celebrate The Clash star Mick Jones turning 55.
The trio was joined onstage by actress Jaime Winstone and British TV presenter Alexa Chung to sing to Jones, who was hosting a bash to celebrate his birthday on Saturday (26Jun10).
The impromptu girl-group then presented Jones with a cake before Moss belted out Blondie song Atomic.
It isn't the first time the aspiring singer has taken to the microphone - she's previously duetted with Beth Ditto and Pink Floyd legend Dave Gilmour.
