Lady Gaga takes another leap with Metallica!

Lady Gaga, Metallica to Duet at Grammys

Lady Gaga will join Metallica onstage at the Grammys this Sunday. On Monday, a Gaga fan site tweeted a snippet of a Grammy promo clip declaring, "Lady Gaga duets with Metallica." Rolling Stone has confirmed the collaboration. This is the latest move in an impressive week from Gaga.

I'm not surprised since Lady Gaga is an admitted 'metal head'   actually I can't wait for this one!
