Natalie Portman looked iconic in Italy at the opening ceremony and "Black Swan" premiere at the Venice Film Festival on Wednesday. She was glamorous in a red gown on the red carpet.

In the film, New York City ballet dancer Nina (Portman) enters into an intense battle of wills with a talented and ambitious new arrival (Mila Kunis) who seems intent on edging her out of the spotlight.

The sexual chemistry between Natalie and Mila is expected to be hot (check out the trailer HERE!)

And Natalie has some ardent female fans, including Katy Perry.

The singer recently talked about the girls she'd like to kiss. She said, "I used to wanna kiss Megan Fox, but now she's married and I'm not so sure about that anymore. Probably Natalie Portman - she's hot and smart."
