Katy Perry at the 2012 Billboard Music Awards at the MGM Grand Hotel and Casino in Las Vegas (5/20)

Katy Perry is really bad at this relationship thing. After dating Florence + the Machine guitarist Robert Ackroyd for about a month, the two have already split up. Probably shouldn't have left the toilet seat up. Asshole. From Us Weekly:

Katy Perry is back on the market -- again. The 27-year-old singer has split from Florence + the Machine guitarist, Robert Ackroyd. The pair started dating about a month ago when they were photographed kissing at Coachella Music Festival.

"It wasn't that serious," a source tells Us Weekly of Perry's relationship with Ackroyd. "It's not a nasty thing and they are still talking, but Katy told him to do his thing and they'll talk soon. No hard feelings. She's really busy and so is he."

So what? Katy Perry has a hole that needs filling. What's Katy supposed to do without Russell Brand's unclipped mutton loaf? Let the girl have her fun, that's what I say. I'm surprised it lasted this long with that dude with the lame band name, but whatever. Katy got a much needed deep drilling, and Robert got a few extra hundred thousand Twitter followers. It's a win/win on both sides . . . kinda. Let's be honest for a second, kids. Bobby Ackroyd will never, EVER, get to motorboat a set of tits like that ever again. Finding a rack like that in a town as fake as Hollywood is like finding the Arc of the Covenant in a New Jersey flea market. Trust me Robert, take up religion.
