Natalie Portman has found love again. The 28-year-old, who has been linked to Gael García Bernal and Jude Law, has quietly been dating Benjamin Millepied, 32, the choreographer of her new movie, Black Swan. Natalie stepped out with her fellow New Yorker for the first time in public at a low-key New Year’s Eve party in Tribeca. “She has been subletting Sarah Michelle Gellar’s apartment and she wanted to celebrate the New Year with a few close friends and introduce them to Ben,” says an insider. “They have actually been a couple since the fall, but she wanted to see how serious it was before she started to show him off to her inner circle. She really likes him.” Black Swan, due to be released later this year, tells the story of two ballerinas, played by Natalie and Mila Kunis. Benjamin began dance training as a child in France with his mother, a dance teacher.
