Couture Fashion Week‘s spring 2011 season in Paris is winding down today, and it’s ending on a high note.

We caught up with Olivia Wilde last night at the Bulgari Save the Children benefit in Beverly Hills, where the star of House and Tron—and one of this year’s Golden Globes presenters—hinted at what she’ll be wearing to Sunday’s big event. “I love this designer; I love them because they are always dramatic, but at the same time elegant,” the actress said of her dress pick. “It’s an American designer and someone who I really admire. It’s outrageous in the way that I think more European designers usually are. I like to pop out at the Globes. I don’t like to blend in, I want to have fun!” Wilde previously wore Gucci and Reem Acra to the Globes, but this year our bets are on Zac Posen, Monique Lhuillier, Carolina Herrera or Marchesa. What do you think? Leave your predictions in the comments!

Katy Perry wore a strapless gold Georges Chakra dress to the Grammy Nominations Concert Live, Olivia Wilde wowed at the Hollywood premiere of TRON: Legacy in a liquid gold Emilio Pucci gown, Anne Hathaway attended the Love and Other Drugs Sydney premiere in this Oscar De La Renta gold sequin minidress, and Shakira wore a gold, one-shoulder number to the Bambi Awards. If you want to try this festive look yourself, take a cue from these stars and keep your accessories to a minimum.
