An actress playing a lesbian is expected to win this year's Best Actress Oscar Award, an insider is predicting.

Three women who play lesbian roles top Dave Karger's “Best Bets” list for the Oscar's Best Actress award.

Portman's portrayal of a lesbian ballerina in Director Darren Aronofsky's much heralded thriller Black Swan “will certainly earn her a Best Actress nomination,” Karger wrote at Entertainment Weekly. The film opened this year's Venice Film Festival. “The other front-runner in the race this year is obviously Annette Bening for her fierce turn as a red wine-loving mom in The Kids Are All Right.”

The third and final actress on the “Best Bets” short list is Julianne Moore, who plays opposite Bening in The Kids Are All Right.

In the film – available now on DVD – the couple's bond is tested when their children seek out their biological father, whose anonymously donated sperm impregnated the women.

The Kids Are All Right is also on Karger's “Best Bets” list for Best Picture.
