Natalie Portman strikes a pose for the February 2011 cover of InStyle Magazine.
The 30-year-old Black Swan star spoke to the magazine before revealing her pregnancy and engagement to the film's choreographer Benjamin Millepied.
"I look for all the same things I would in a friend," Portman tells the mag about her ideal mate. "Obviously, you need the sexual attraction too, so it's like your best friend who you are also really attracted to."
Portman will next be seen alongside Ashton Kutcher in the romantic comedy No Strings Attached, out January 21.
She was photographed by Michelangelo di Battista for these stunning photographs.
