Olivia Wilde's husband gets turned on when she kisses other men.

The 'Tron: Legacy' actress says spouse Tao Ruspoli isn't the jealous type so isn't concerned when she has to lock lips with her hunky co-stars in her movies.

She said: "I think he likes it. It's a turn-on that I get to do these things."

Olivia and filmmaker Tao - son of the late Italian Prince Dado Ruspoli - met when she was just 18 and the pair married got married after just six months of dating and she admits it wasn't a conventional wedding.

She said: "We eloped. There was nothing traditional about it."

The 26-year-old beauty believes one of the reasons their marriage is successful is because they don't put too much pressure on themselves.

She explained in an interview with Women's Health magazine: "You're not thinking, 'We must be perfect!' It was, 'Hey, isn't this an optimistic thing to do? And if it lasts, we're lucky.' "

Thanks to her role in 'Tron' Olivia is now regarded as one of the world's sexiest women, but she admits she had to work hard to get her hot body.

She said: "I worked with a personal trainer, so I did about an hour of cardio five or six days a week, weight training three times a week, mixed martial arts/fighting three times a week, and that's a lot more than my normal routine!"
