Singer Summer Walker and London On Da Track -- who produced much of her hit debut album Over It --had been dating.

Last week, they broke up, with Summer Walker accusing London of chauvinistic behavior. 

"Single. Lol somehow I always end up with male chauvinist. Im a alpha female so I guess when I think for myself/make my own decisions it's taken as disrespect," she wrote on social.

It's probably just a little lover's spat, and they've been spotted back together since.

But it was enough for Joe Budden to have a theory about what happened.

"I'm going to just say it. It was Aubrey. Let's not even get to Aubrey's DM for a minute," Budden said of a publicized  DM that Drake sent her complimenting her new album. 

Budden then broke down Walker's "chauvinist" message, arguing that London must have pressed her on Drake's emoji-filled message, feeling a certain way about Drake's jumping in and talking about an album that he is largely responsible for. She didn't like that being an "alpha", thus the public breakup.

Jump to 58 minutes to hear Budden's argument. Do you think it's valid, or does Budden just see his guy "Aubrey" hiding in every corner?
