Actress Jennifer Aniston is rumoured to be dating her co-star from the upcoming movie "The Break Up", Geoff Stults.

Aniston, 36, who recently divorced from her husband, actor Brad Pitt and said a few days ago that she's ready to date, was spotted flirting with her colleague, Geoff Stults, on the set of "The Break Up", according to US tabloid National Enquirer.

A set source says, "During the final weeks of filming in Chicago, she (Aniston) flirted outrageously with Geoff.

Everyone couldn't help noticing the sexual undercurrent between them... At a buff six foot three (inches), Geoff looks like a super-sized version of Brad."

Just three days ago, Jennifer confessed during the "The Oprah Winfrey Show" that she has recovered after the divorce and she's ready to start a new life.

"I'm doing so well. I don't want to be anywhere else than where I am right now," she said. "I'm not sitting somewhere dwelling on the past or obsessing about something in the future."

And when Oprah asked her if she's ready to date again, the actress emphatically replied, "yes" and looked at her watch, as if to say it was time.

Geoff Stults, born 15 December 1977 in Michigan, appeared in movies like "Wedding Crashers", "Confessions of an American Bride", "Bring It On Again" and acts in the long running show, "7th Heaven" (1996), in which he plays Ben, the brother of Kevin Kinkirk.
