Katy Perry's Grammy Performance -- And Other Award Show Acts Aimed At Exes

Katy Perry's Grammy performance last night seemed like a very public message to ex-husband Russell Brand. In "Part of Me," she sang: "You rip me off your love was cheap I was always tearing up the sheets ...You can keep the diamond ring, You ain't doing nothing anyway." The take-charge message was a far cry from her 2011 Grammy act, when she debuted her wedding video as a backdrop.

Rihanna's rendition of "We Found Love" -- which immediately followed a lacklustre showing by her ex and rumored attacker Chris Brown, dancing on what appeared to be a giant set of legos -- also showed her ex that she's just fine, thank you very much.

This wasn't the first time the Grammys have been used as the ultimate stage to air your breakup grievances (and show your ex you're still looking pretty good, too). While the rest of us have to resort to Twitter and Facebook, these stars have a chance to send the message home to millions. Here are some favorite Grammy performances inspired by breakups.
