This is pretty random. Chief Keef seems to have some beef with Katy Perry, and vice versa. The singer heard Keef's single "Hate Being Sober" on the radio this week, and she was so unimpressed by it she had to take to Twitter to express her feelings.

The singer tweeted, "Just heard a new song on the radio called "I hate being sober" I now have serious doubt for the world." When Chief Keef caught wind of this shot, he did not hesitate to fire back at Ms. Perry.

Today, the Chicago native tweeted, "Dat bitch Katy Perry Can Suck Skin Off Of my Dick." He continued to say he'd "smack the shit outta her," and then revealed he has a new song called "Katy Perry" coming soon. That song should be a pretty interesting listen.
