Jennifer Aniston broke down after a love scene reminded her of Brad Pitt.

The Hollywood actress — whose marriage to the 'Inglourious Basterds' hunk ended in 2005 — was apparently so distraught about the romantic scenes with her 'The Bounty' co-star Gerard Butler, she fled to her trailer in tears.

She reportedly told her assistant: "I need a moment. This scene reminds me of Brad and me."

On set sources claim this wasn't a one-off incident and the 40-year-old actress — who has remained single since she was dumped by singer John Mayer earlier this year — was "very fragile" during the last few months of filming.

The source added to the New York Post newspaper: "While she enjoyed flirting with Gerard on set and put a brave face on every day, privately she is still very fragile."

During production, Jennifer was romantically linked with Gerard (38) after they were seen holding hands while on a dinner date in New York.

When Jennifer and Brad's five-year union ended, there was speculation this was down to his growing closeness to his 'Mr. and Mrs. Smith' co-star Angelina Jolie — with whom he now raises six children.
