Anne Hathaway has reminded everyone of her vocal power, and how good 'Since U Been Gone' is with a brilliant performance during 'The Kelly Clarkson Show'.
The two celebrities were going head-to-head in a game called 'Name That Tune', where each star was tested to work out the song Kelly Clarkson's show band was playing, in order for their audience to win prizes.
The actress took the game early on, figuring out 'Piano Man' and 'Mmmbop' while Kelly kept struggling.
And in a twist of irony, before her "Name That Tune" started, Kelly asked her band, "Can y'all play a frickin' song I'll know?!"
It only took a few "bom bom boom booms" for Anne Hathaway to take the song, and bring Kelly to the floor in complete shock that she lost on her own song.
"Kelly Clarkson, if you do not understand how much we all love that song Everybody here knew it on the first [note]," Anne Hathaway told her competitor, who swore in frustration.
