Brand 'romancing Hugh Hefner's ex-love'

Russell Brand has reportedly been spotted romancing Hugh Hefner's ex-girlfriend in Las Vegas.

According to E! News, Brand was seen enjoying dinner with Girls Next Door star Holly Madison at P. Diddy's table at TAO, where Jay-Z was hosting a "fight-night party".

An onlooker said that the duo "were flirting with each other all night".

The couple were joined by Cassie, David Arquette, Brothers & Sisters star Balthazar Getty and Spice Girl Mel B.

Brand split from actress Teresa Palmer last year, while Madison parted ways with Vegas-based illusionist Criss Angel in February.
