So Russell Brand isn't really in love with Isabella Brewster, instead, it appears that they may just be friends with benefits. A source told Hollyscoop:
"He has been seen a lot with Isabella Brewster, but she is just a f*ck to him."
Apparently this is a source of conflict for the pseudo couple, because Russell is willing to bang any hot girl he can and Isabella has feelings or whatever. One of his other hook-up babes is his on-again, off-again stylist who is apparently "obsessed with him," whatever that means.
His other "friend with benefits" is "some fangirl that he has been banging all the time," adds the source. Our source adds that he'll have girl #1 over as girl #2 is walking out the door.
