JENNIFER ANISTON - ANISTON DATING DERAILED CO-STAR?

Movie beauty JENNIFER ANISTON has fuelled speculation she's dating her DERAILED co-star VINCENT CASSEL by spending most of her free time with the French actor.

The 35-year-old actress - who ended her four-year marriage to actor BRAD PITT earlier this month (JAN05) - became close to 38-year-old Cassel while filming their latest movie on location in Chicago and London.

And the relationship has continued in Los Angeles, where post production work on the film continues, reports British newspaper the DAILY STAR.

A close source says, "There's real chemistry between them. When they're together they speak almost in whispers, with eye contact all the time.

"Sometimes she will give that laugh, broad smile and play flirtatiously with her hair. If pressed, she'll tell you that Vincent is very close and very dear to her. But he seems much more than an agony uncle."
