Annette Bening and Mark Ruffalo, stars of the lesbian moms flick The Kids Are All Right, have won New York Film Critics Circle Awards for their performances.

Bening won the group's Best Actress award for her portrayal of Nic, a woman raising two children with her partner Jules, played by Julianne Moore.

The group gave their Best Supporting Actor award to Ruffalo (Eternal Sunshine of the Spotless Mind, Shutter Island), who plays the biological father of the children in the movie.

And the film's scriptwriters, Lisa Cholodenko and Stuart Blumberg, received the award in the Best Screenplay category.

In the film, directed by Cholodenko and available now on DVD, the family dynamics are altered in unexpected ways when the couple's teenage children seek out their biological father.

The group's annual awards presentation will take place in New York City on January 10.

Moore and Bening are considered front-runners to be nominated in this year's Oscar Best Actress award. Also expected to be nominated in the category is Natalie Portman (Star Wars) for her portrayal of a lesbian ballerina in Director Darren Aronofsky's much heralded thriller Black Swan.
