Russell Brand Reportedly Dating Isabella Brewster

Katy Perry and Russell Brand are officially single as their divorce was finalized on July 16, but Brand reportedly has a new lady in his life.

Us Weekly reports that the British comedian recently began dating Isabella Brewster -- the younger sister of "Dallas" star Jordana Brewster.

According to one insider, the two have been seeing each other for a few weeks. And "he really likes her," says the source.

Isabella is a former CAA talent agent, who before dating Brand was linked to actor Milo Ventimiglia in 2010 and "The Hangover" star Bradley Cooper in 2009.

Tweets from an unverified Twitter account that appears to belong to Brewster also seem to confirm that the two have been seeing each other for some time. On July 1, Brewster wrote, "Good times at BRAND X taping with @JessaPlum @jimhecht @ColetteCrazy ‪#BrandX,‬" referring to the 37-year-old comedian's new late-night series on FX.

Brewster isn't the first woman Brand has been linked to since his split from Perry back in December 2011. In February he was linked to artist and model Oriela Medellin, whom he reportedly met at a yoga class, and in March he was rumored to be dating model Nikolett Barabas.

Meanwhile, Brand's ex-wife has also moved on with her love life. The 27-year-old had been linked to Florence + The Machine guitarist Robert Ackroyd, after the two were spotted getting close at Coachella in April, but she insists she's not ready to dive into anything serious.

"That's not even appropriate to label," she told USA Today about her relationship with Ackroyd, which has reportedly cooled off. "There are times I go out and meet people and flirt, but it's not really appropriate to have anything serious."
