The first thing Rebecca Romijn notices on the boat is the cage - you know, the one that will stand between her and
a sea full of circling sharks. It is constructed of PVC tubing. It lies, folded, on the deck. And, with apologies to whoever constructed it, it does not appear to be an impenetrable fortress of protection.

"I mean, it's plastic," Rebecca smirks. "I have beach chairs that look sturdier than this."

Rule 1: Instant head clearer: handstands
"I do them anytime I feel nervous or need to be 'on.' Being upside down gets blood and oxygen to the brain, so I can think more clearly. Before I go on talk shows, I do handstands in my dressing room. Once, I was doing one right before Jimmy Kimmel Live, but I knocked over a lamp and totally tore up my knee. I never said I was good at them. I practically limped on to that show."

To the average woman, these three actresses look so effortlessly beautiful, you'd swear they had superpowers - and that's before they put on their costumes. Halle Berry, Rebecca Romijn and Famke Janssen all play mutants in this month's X2, but these are mutants who make men swoon. The sequel to X-Men (2000's blockbuster sci-fi tale), X2 reunites three former models who have surprisingly down-to-earth views about the otherworldly life inside the Hollywood bubble.

Where you've seen her:
One of the world's hottest supermodels, she has graced numerous magazine covers but it was on MTV's House of Style where she made her celluloid breakthrough. A burgeoning career as an actress soon followed with parts in Austin Powers: The Spy Who Shagged Me, X-Men and Rollerball. She now heats up the silver screen as a sultry jewel thief in sexy thriller Femme Fatale.
