Remember how Katy Perry, singer of binge drinking anthem 'Last Friday Night (T.G.I.F.),' called out rapper Chief Keef indirectly over Twitter after she heard his track 'I Hate Being Sober' on the radio?

That didn't sit well with Keef, who isn't known for having the best judgment.

On Thursday (May 23), Perry posted, "Just heard a new song on the radio called 'I Hate Being Sober.' I now have serious doubt for the world."

Keef responded in a pretty vulgar manner, writing, "Dat b---- Katy Perry can suck skin off of my d---." He added, "Ill Smack the s--- out her."

Then, maybe most ominously:

Perry, perhaps sheepish and intimidated but likely just over it, tried to quell the drama with the teen father.

Keef then proceeded to tweet about wanting to have sex with Reggie Bush's Kim Kardashian look-alike baby mama, and all was right with the world.

Weird, we thought they'd work all of this out over a few beers.
