Angelina Jolie has been told to pile on the pounds for her latest film role.

The 33-year-old actress must gain up to 28lbs by the bosses of 'The Thomas Crown Affair 2' - who she also worked with on her last movie 'Wanted' - because they are desperate to avoid her fainting on set as she did while filming the assassin thriller.

A source said: "Ideally they want Angelina to put on 28lbs for the role. It is going to be very physically demanding, which is why they want her to carry the extra weight."

"They don't want a reprise of what happened with 'Wanted', where she was fainting and they had to take her costumes in. She was also slated for being too skinny to portray an action woman, and for 'Thomas Crown' they want a convincing female lead."

Angelina - who gave birth to twins Knox Leon and Vivienne Marcheline earlier this month - is due to play the leading lady opposite Pierce Brosnan, who reprises his role as billionaire art thief Thomas Crown.

Brosnan will also produce the movie.
