Bathing beauty Natalie Portman wears a VERY tiny bikini in new film

She's worked hard to develop a reputation as a serious actress, but now Natalie Portman is revealing her cheeky side. The 29-year-old actress peels down to a very tiny bikini in her new film, Your Highness. The role comes hot on the heels of her risqué lesbian scenes with Mila Kunis in new film Black Swan.

Natalie has been embracing some very risque role choices recently

In recently released stills, Natalie 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. Your Highness is a comedic action/adventure set in medieval times, and also stars James Franco, Danny McBride and Zooey Deschanel.

Natalie recently played a lesbian ballerina in psychological thriller Black Swan

Relations between Natalie and her Israeli doctor father Avner Hershlag were said to be ‘very frosty’ following the sexually explicit scenes in Black Swan. The Star Wars actress has previously turned down roles, including Lolita, which she considered too explicit. But she was determined to take on the role of troubled prima ballerina Nina in Black Swan. ‘Natalie is a very private and dignified person and is often influenced by her father’s approval,’ said a source.

‘This, however, was one role she simply didn’t want to turn down even though she knew it would upset her father. ‘He still sees her as his baby and always will and thinks showing herself like this is degrading. 'Things are very frosty between them right now.’ Your Highness is due for release in April 2011.
