Meek Mill launched Twitter war against Drake because of affair with Nicki Minaj?

That's what a source is claiming. This morning Meek Mill fired at one of Nicki's closest allies in the music business, Drake, claiming that Drake doesn't write his own lyrics. A source claims that Meek came for Drake on Twitter after he found out that Nicki had dated Drake in the past.

"Meek is upset that Drake [allegedly dated] Nicki. I think Nicki is low key in love with Drake and Drake is low key in love with Nicki. You have to see how they are when they're around each other. If I was Meek, I might feel some type of way about it too."

MediaTakeOut claims the alleged relationship between Nicki and Drake occurred while she was Safaree . . . but when she was also creeping with Meek.

"Meek is very insecure, and he should be. He got Nicki on the rebound . . . she just came off a long-term relationship with [Safaree] and you know sh*t like that [rebound relationships] never really work.

"Real talk though - I think Nicki and Drake really will get married one of these days." the source told MTO

Meek Mill has since deleted most of Nicki's photos from his instagram page...
