Katy Perry set off fireworks and angered Chief Keef by dissing his music, but now the pop queen has apologized to the 17-year-old Chicago rapper.

It all started on Tuesday when the "Wide Awake" singer logged onto Twitter to voice her opinion about Keef's music. "Just heard a new song on the radio called 'I hate being sober' I now have serious doubt for the world," she wrote.

Keef caught wind of the jab a few days later, and on Thursday night he got fans everywhere talking with his foul-mouthed and threatening response. "Dat bitch Katy Perry Can Suck Skin Off Of my Di--," he wrote. "Ill Smack The Sh-- out her."

He also revealed plans to drop a Katy dis song, but Katy's apology may force the rapper to have a change of heart. "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 responded, referencing the Wiz Khalifa and 50 Cent features on Keef's "Hate Bein' Sober." "Actually... 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, I'm a lover not a hater. x"

The controversial rapper eventually accepted the apology, responding "@katyperry Oh Im Sorry Too Then."
