Just one day after his divorce from singer Katy Perry was finalized, comedian Russell Brand has a new girlfriend: Isabella Brewster, the younger sister of "Dallas" star Jordana Brewster.

Us Weekly reported on Tuesday that 37-year-old Brand has been dating Brewster for a while now, after photos from late June circulated of the couple holding hands in West Hollywood, Calif.

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

Brewster and Brand were also seen Sunday walking around Pacific Palisades Market, The Daily Mail reported. Brewster, said to be 30-years-old, also tweeted about being on the set of Brand's new television show, "Brand X," earlier this month.

"Good times at BRAND X taping with @JessaPlum @jimhecht @ColetteCrazy ‪#BrandX," she wrote on July 1.

Another source told Radar Online the couple share a few things in common but Brewster is remaining alert while dating the British playboy.

"Isabella and Russell... are both in recovery and totally into yoga, so they have definitely found common ground. They are really enjoying spending time together," the source told Radar. "Isabella really likes Russell and loves dating famous people, but she knows that he is a ladies man so she is trying to play it cool."

Brand and 27-year-old Perry announced their split in December and the divorce was finalized on July 16.

So who is this new girlfriend anyway?

According to Us Weekly, Isabella Brewster is a former CAA talent agent and has dated the likes of Bradley Cooper in 2009 and Milo Ventimiglia in 2010.

But Brewster might not be the only woman in Brand's life. Some reports indicate that Brand has dated Oriela Medellin and model Nikolett Barabas since his split from Perry, but neither has been confirmed nor denied.

Katy Perry and Russell Brand spent 14 months married and tied the knot in a luxurious wedding in India.

Meanwhile, Perry is said to be dating the guitarist of Florence + The Machine, Robert Ackroyd after being photographed kissing Ackroyd in April at the Coachella Valley Music and Arts Fesitval in Indio, Calif.

"That's not even appropriate to label," Perry told USA Today of dating speculation. "There are times I go out and meet people and flirt, but it's not really appropriate to have anything serious."

However, Katy Perry is not giving up love in light of her divorce.

"I still believe in love, most definitely. I'm just going to let that take the lead," Perry said in an interview promoting her upcoming 3D movie.
