star Carla Gugino has no problem showing off her curves, but the actress believes true beauty is more than physical.
"The people who are the most beautiful are those who do what they love to do – who have love in their lives, and laugh a lot, go to good movies, read good books, and have great sex," the actress, 37, told Women's Health
for its March issue.
Gugino, one of the magazine's cover girls (costar Malin Akerman appears on a separate cover), stars as a sexy burlesque dancer-turned-superhero in the upcoming film The Watchmen
Many of Gugino's past roles also have featured a sexual element, and she says working with men has been "a positive thing."
"A guy who’s a chauvinist I’m not interested in," she tells the magazine. "Any good man knows women are much smarter than men."
And that likely includes her screenwriter boyfriend, Sebastian Gutierrez – though the pair have no plans to marry.
"[Marriage] isn't important for us. We like being boyfriend and girlfriend; there’s something sexy and fun about that," says Gugino. She adds, "We're very much about, 'There’s nothing holding us here other than our desire to be together.'"
