Jerry O'Connell has stepped in to train his girlfriend Rebecca Romijn for the third X-Men movie when it starts shooting next month (August 2005). The actor has picked up enough tips from his brother Charlie, who used to be a professional fitness trainer in Hollywood, to set his girlfriend a rigorous work-out schedule, so she'll look great when she reprises her role as all-blue Mystique.

Romijn feels it's the least her man can do - as he's partly responsible for her weight gain, which has got gossips speculating about her health for the past few months. She explains, "I've had a great year with my boyfriend. I fell in love and had lots of romantic dinners. It was worth every last chocolate mousse and bottle of wine. But now it's crunch time."
