Katy Perry Apologizes to Chief Keef After Rapper's Hostile Response to Her on Twitter

Singer disses his "I Hate Being Sober," then Keef tweets that he'll "Smack The S—t out of her"

Katy Perry found herself in an unlikely Twitter feud with rapper Chief Keef earlier this week.

On Tuesday, the 28-year-old pop star tweeted her disapproval of Keef's song "I Hate Being Sober," a NSFW track also featuring 50 Cent and Wiz Khalifa. Instead of brushing off the criticism, Keef (real name: Keith Cozart) blew up, spewing hateful epithets at Perry on the social networking site.

What started it all was when Perry tweeted, simply, "Just heard a new song on the radio called 'I hate being sober' I now have serious doubt for the world"

It took 17-year-old Keef a few days to take note of Perry's diss. He tweeted a lewd suggestion, and added, "Ill Smack The S--t out her."

The "Wide Awake" singer responded to the harsh words, but she took a much classier approach. "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 wrote.

"Actually...," she added, "I'm a fan of your 'Don't Like' video tbh. I was really just having a general opinion on our generations desire to be constantly intoxicated."

"Believe me," she wrote. "I'm a lover not a hater. X"

Keef retweeted Perry's kind messages, then wrote to her, "Oh Im Sorry Too Then"

Well that was…decent.
