There's a new matchmaker in Hollywood.

Stepping to the stage Friday night in L.A. to accept the Best Actress prize at the Critics' Choice Awards, Natalie Portman wasn't about to stop at thanking Darren Aronofsky for directing her in 'Black Swan.' He also got credit for the on-set romance that led to Portman's pregnancy.

"I have to thank you for this incredibly fulfilling experience," she said to Aronofsky, who was beaming in the celeb-packed audience. "You made me very skinny, and now you're indirectly responsible for getting me fat....You introduced me to my love, Benjamin Millepied, who also choreographed the film, and I am so incredible grateful for that most special of gifts."

Portman, 29, also joked about her long friendship with her director. "I met you 10 years ago in a HoJo in Times Square," she said. "You were classy then, you're keeping it classy now."

Other big Critics' Choice winners included Colin Firth ('The King's Speech') for Best Actor, as well as Christian Bale and Melissa Leo for their supporting roles in 'The Fighter.' David Fincher was named Best Director for 'The Social Network,' which also won Best Adapted Screenplay (Aaron Sorkin) and Best Picture. 'Toy Story 3' was deemed Best Animated Feature, while 'Waiting For Superman' won Best Documentary.
