Russell Brand's Already Seeing Other Women And Slamming Katy Perry!?

What!?! No! Nooo!!!

We cannot believe this. How tacky!!

According to some insiders, Katy Perry heard through a friend that Russell Brand is not only seeing other women already, but he's trash-talking Katy too!

But wait! It gets worse!! The source says:

She discovered through her friends. One of the women told a friend of hers and it got back to Katy. He's spoken terribly about Katy to them. [He wants to] explore a relationship [with one of them. He told her he wanted her to move in with him after the divorce is final.

Ugh!!

Okay, first of all, it seems like he's definitely not over Katy. Clearly the love is gone, but if he's slamming her, there must be some feelings he hasn't dealt with.

And second, move in with a girl the second the divorce is final?? Trying to fill a void asap, huh??
