Olivia Wilde would need "four vaginas" to date all the men she is linked to.

The 'Tron: Legacy' actress - who has previously married to Tao Ruspoli and was recently linked to 'Hangover' actor Bradley Cooper - believes she could never have been with all of the men it has been claimed she is with as her anatomy could not cope.

She said: "In order to be dating all the people they think I am, I'd need four vaginas! It's impossible!"

Now the 27-year-old beauty is more confident in herself, and now believes all new actresses should try and be "themselves".

She told Allure magazine: "I went through this kind of 'Star is Born' transformation, where they made my hair very blonde, and I got very skinny, and I was like, 'And now, I fit the mold!'

"If I could tell young actresses anything, it would be to just be yourself through and through, I mean, really be hardcore about sticking to your identity, because what makes you unusual is what's going to assure your success."
