Celebrity Karaoke: Joseph Gordon-Levitt Channels Axl Rose, Jimmy Fallon Does a Mean David Bowie
First Fallon delivered Foster the People's "Pumped Up Kicks" dead-on. Then Gordon-Levitt got onstage for his version of Kelly Clarkson's "Since U Been Gone," Axl Rose-style. And then it was a Lady Gaga duet: the duo traded off lines on "Edge of Glory" as Bowie and Rose. It was awesome; watch it after the jump.
