Russell Brand officially dating Bradley Cooper's ex

Just days after his divorce was officially finalised, Russell Brand has confirmed he is dating Isabella Brewster, the sister of Fast and the Furious star Jordana Brewster, and serial celeb dater (her exes include Bradley Cooper and Heroes actor Milo Ventimiglia).

In an interview on Howard Stern's radio show, Russell revealed he is dating former Hollywood agent Isabella.

"Some things in the newspaper are untrue. That's true actually," Russell said.

A source told Us Weekly the pair have been together for "a few weeks", and "he really likes her".

But Russell was quick to add that he is "just kind of enjoying the freedom" of being single again.

Russell spoke candidly of his just-official divorce this week while promoting his new TV show BrandX on CNN.

"I think what happened at the weekend was an administrative finality, so I don't think that it makes very much difference," he said.

"Of course I still feel great feeling of compassion and warmth for Katy, but I'm very happy with my life."

Russell added that mediation, yoga, and his TV and movie projects are keeping him content.

Katy is rumoured to be dating Florence + The Machine guitarist Rob Ackroyd, but the 27-year-old pop star has dismissed claims it's anything serious.

"There are times I go out and meet people and flirt, but it's not really appropriate to have anything serious," she told Us Weekly.

It's great that Katy and Russell are keeping their divorce clean, unlike these messy celebrity break-ups ...
