Featuring her new song "Part of Me," Katy Perry's Grammy performance contained what many felt was a thinly-veiled shot at Russell Brand Sunday night.
Rihanna and Coldplay joined forces in a performance of "Princess of China" that didn't generate as much controversy, but was still very well received.
Which of the two stars will perform better in a red carpet style showdown, though? That's the question of the hour. At least on The Hollywood Gossip.
Rihanna, as you can see, showed serious skin. Katy? Not so much in a blue gown that matched her hair (obviously). But she made up for that later.
Who will win this couture clash of the pop star BFFs?! Your votes will decide. Choose your favorite style star in our latest Grammy Awards Fashion Face-Off!
