Justin Bieber is gonna have to do a lot more than say he's sorry to get out of this one!
Yikes! This could get ugly.
Take a listen to both songs (below) to hear the very recognizable riff!
Hands down, one of the best performances of the evening!
Check out Rihanna's stunning rendition of We Found Love, before she was joined on stage by Coldplay to sing their duet, Princess of China, and then the band's single, Paradise, at the 54th Grammy Awards (above)!
She looks - and SOUNDS - incredible, and of course, Coldplay are just PROS!
