Russell Brand is dating Hugh Hefner’s ex-girlfriend.

The British comic star has been spotted making late-night visits to the Hollywood home of Playboy Playmate Holly Madison, who split from the Playboy founder last year.

Holly, 29, and Russell, 33, met at a party thrown by rapper Jay-Z in Las Vegas two weeks ago.

Friends say the pair couldn’t keep their eyes off each other and have been meeting up in Los Angeles - where Russell is shooting new film Get Him To The Greek - nearly every night since.

A source said: “Russell has really hit it off with Holly. She’s a big star in the US, which he finds really attractive.

“And his humor makes her laugh all the time. Russell has been making late-night visits to her home in the Hollywood Hills.

“He’s been there three times in the past week.”

Holly - who appeared on the latest season of US TV talent show Dancing With The Stars lived with Hefner, 83, in his infamous Playboy Mansion for seven years.
