Natalie Portman sports a bikini on screen for the first time

London: Hollywood beauty Natalie Portman had vowed never to strip for the cameras but she will be seen donning a bikini for the first time on screen in her upcoming film ‘Your Highness’.

The role comes hot on the heels of her graphic lesbian scenes with Mila Kunis in her new film `Black Swan`.

The 29-year-old peels down to a very tiny bikini in the comedy `Your Highness`, where she stars alongside James Franco and Zoey Deschanel.

In recently released stills, the Oscar nominated actress is seen stripping down into a very skimpy two-piece as she stands on some rocks next to a large pond surrounded by trees.

The green thong bikini leaves nothing to the imagination, emphasising every curve of her enviably toned body, reported Daily Mail online.

The `Star Wars` actress has previously turned down roles, including `Lolita`, which she considered too explicit.
