Dave Grohl became the latest star to share the stage with The Rolling Stones when he joined the rockers at their show on Saturday (18May13). The Foo Fighters frontman was a surprise guest at the band's sold-out concert in Anaheim, California, where he was brought out unannounced to play guitar and share vocals with Sir Mick Jagger during Bitch. British DJ Fearne Cotton, who has a baby boy with guitarist Ronnie Wood's son Jesse, was among the fans at the Honda Center who went wild when Grohl turned up. In a post on her Twitter.com, Cotton tweeted, "I thought the show couldn't get any better and then Grohl walked out! Dream gig..." There's been no shortage of famous faces onstage at The Rolling Stones' ongoing 50 & Counting tour - Katy Perry, John Fogerty, Gwen Stefani, Keith Urban and Tom Waits have all appeared at previous concerts.
