JUDE LAW - LAW'S GIRLFRIEND BULKS UP FOR FILM ROLE

JUDE LAW's girlfriend SIENNA MILLER is bulking up for her starring role opposite HEATH LEDGER in forthcoming movie CASANOVA.

Miller - who is set to play the love interest in the $72 million (GBP40 million) film - is having to build up her physique with a tiring regime of sword-training.

An insider explains, "I've heard that there's a lot of sword-fighting involved. Not only is Sienna having to take loads of lessons, but she's also having to get a little bit stronger."

The romance, to be released by studio TOUCHSTONE, is about a famed seducer who learns the meaning of true love when he meets a woman immune to his charms.
