Earlier this week, hit-making machine Katy Perry heard a Chief Keef track on the radio and tweeted her disgust over its "Hey bud, let's party!" message.

Well, the track is a little more salacious than that—it's called "Hate Bein' Sober"—but given it's from a teenage rapper, "I like to party" is essentially the message. "I now have serious doubt for the world," Perry tweeted, seemingly forgetting she has a No. 1 hit about getting blackout drunk.

Keef—never an MC to play nice—got wind of the diss last night and started taunting her on Twitter will the fervor and vocabulary of a playground bully. "Dat b-tch Katy Perry can suck skin off of my d-ck," he generously offered, in addition to threatening to "smack the sh-t out of her."

With Twitter as our witness, that barrage actually elicited a heartfelt apology from Perry for slamming his song. "Mr. Keef! I'm sorry if I offended you. I heard a lot of people guesting on the song & didn't even know it was you in particular," she tweeted. Perry added she's a fan of his "I Don't Like" video (but really, who isn't?) and explained her distaste for the track was more about "our generation's desire to be constantly intoxicated."

Keef seemingly took the olive branch, retweeting her apologies without comment and soon went back to more important issues: Telling the world who he'd like to bang. "No lie I wanna f-ck Reggie Bush baby mama dat look like Kim K," Keef revealed.

All is right with the world.
