Russell Brand's divorce from Katy Perry finally became official yesterday, and he certainly hasn't wasted any time with moving on.

On the same day he finally became free of his marriage, he was spotted in a Pacific Palisades farmer's market with actress Jordana Brewster's sister, Isabella, a former talent agent at CAA.

"It's been going on for a few weeks," an insider told Us Weekly. "He really likes her... She is all over him and Russell loves it."

This is not her first actor conquest, though. Isabella reportedly dated Bradley Cooper in 2009 and Milo Ventimiglia in 2010.
