Wiz Khalifa and Kanye West got into it on Twitter, first over the name of West’s new album Waves and then it got extremely personal.

Khalifa was previously married to Amber Rose, who West dated before he married Kim Kardashian. In a series of tweets, the “All Day” rapper told Khalifa he’s the reason he even has a child with Rose.

It all started when Khalifa tweeted about Waves, writing, “Please don't take the wave. Max B is the wavy one. He created the wave. There is no wave without him.”

West took offense and went off on the “See You Again” rapper with 17 reasons he shouldn’t have taken a hit at him. He was also noticeably upset with Khalifa tweeting his wife’s initials “KK.”

Khalifa responded by telling West “KK” stands for marijuana, not his wife but West continued to rant that Khalifa stole his style from Kid Cudi and his music is “corny as f—k.”

He continued on all the way through 17 and then some, warning Khalifa not to mention Kardashian or his family. He also told Khalifa he should respect him as an “OG.”
