Michael Bublé and Foo Fighters Team Up for Surprise Performance

Michael Bublé made a surprise appearance during the Foo Fighters’ set at Outside Lands in San Francisco. In what was part of a long-running gag, Foo Fighters frontman Dave Grohl asked the audience if they know the words to the singer’s 2009 single, ‘Haven’t Met You Yet,’ while introducing the crowd to drummer Josh Freese. This time, Michael posed as a fan and popped up in the audience holding a sign, reading, ‘I [heart] Bublé.’
