Pink and Alicia Keys are both pop superstars, but Pink has more of a rock edge.  It's no wonder she's brought a cool rock 'n roll spin to a new cover of Alicia's current hit "Girl on Fire."

On Wednesday, Pink appeared on BBC Radio 1's Live Lounge , which always invites artists to cover other artists' songs.   She chose "Girl on Fire," but replaced the piano in Alicia's original version with hard-rocking, fuzzed-out guitars.

Pink will kick off her Truth About Love tour February 13 in Phoenix, Arizona.
