Katy Perry and John Mayer leaving the Chateau Marmont in West Hollywood (2/10)

Honestly, Katy Perry and Rihanna need to get over their difference and kiss and make up. With tongue. Lots and lots of tongue. From Us Weekly:

Rihanna's reunion with Chris Brown at this year's Grammy Awards stirred up plenty of buzz among fans, but it turns out that some of the couple's famous friends aren't so hot about their rekindled romance either. Katy Perry, who got close with the "Stay" singer at last year's Grammys, "doesn't approve" of Rihanna's decision to get back together with Brown, 23, and their friendship has suffered as a result of it, sources tell Us Weekly.

"They aren't tight anymore because Katy doesn't approve of Rihanna dating Chris Brown," an insider told Us of the pair.

Perry, 28, instead spent the evening on the arm of her beau, a maroon suit-wearing John Mayer, 35. The couple had a front-row view of the night's performances, while Rihanna and Brown cuddled up elsewhere in the audience.

I have to admit that, a few months ago, I was suffering a bit from Katy Perry overexposure, but lately she's been on fire, blasting those awesome tits all over the place. And for the icing on the cake, Katy is letting it be known that she's not all in with this Chris Brown jerk-off like the rest of the spineless, testosterone-deficient music world? Awesome. Is Rihanna one of those gals who needs to be corrected vigorously on occasion? Probably, but I don't know. What I do know is that Chris Brown is an asshole, Katy Perry needs to show more cleavage, and Rihanna should cover up that goddamned giant forehead of hers. Good God, it looks like a bowling ball stretching a condom.
