London, Sep 24 - Jennifer Aniston broke down after a love scene in her new movie 'The Bounty' reminded her of her ex-husband Brad Pitt.

Contactmusic.com reports that the actress, whose marriage to Pitt ended in 2005, was apparently so distraught about the romantic scenes with Gerard Butler in her new film that she fled to her trailer in tears.

'I need a moment. This scene reminds me of Brad and me,' she reportedly told her assistant.

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

'While she enjoyed flirting with Gerard on set and put a brave face on every day, privately she is still very fragile,' said the source.

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