Despite the fact that his divorce from pop star Katy Perry only became official on Monday, Russell Brand is reportedly "head over heels" in like with Isabella Brewster, the younger sister of Dallas star Jordana, US Weekly reports.

"It's been going on for a few weeks," an insider told the magazine. "He really likes her."

This wouldn't be the first actor that Isabella has dated. Previously, she's been connected to Bradley Cooper in 2009 and Milo Ventimiglia in 2010.

For her part, Katy isn't interested in dating anyone. In fact, in a recent interview with USA Today, the singer declared, "There are times I go out and meet people and flirt, but it's not really appropriate to have anything serious."

Celebs being so flippant over marriage and relationships shouldn't surprise me but to be honest it does.  I don't get it, never will.
