Jennifer Aniston's rep has dismissed claims she burst into tears over Brad Pitt while filming The Bounty with Gerard Butler this summer.

According to Page Six, the actress was caught crying in her trailer by an assistant who went to fetch her when she was late to the set.

She is alleged to have said: "I need a moment. This scene reminds me of Brad and me."

The Friends star eventually emerged from her trailer looking chirpy but, says the insider: "While she enjoyed flirting with Gerard on set and put a brave face on every day, privately she is still very fragile."

Jen's spokesman, Stephen Huvane, says the story is "ridiculous...it never happened." But then he would, wouldn't he?

A string of failed relationships since splitting from Brad in 2005 has earned Jen her 'unlucky-in-love' tag.
