Katherine Heigl was beaming as she walked the red carpet Monday night for the premiere of her new feature comedy, 27 Dresses (in theaters Jan. 18). Also on hand for the first look were Grey's Anatomy cast mates Ellen Pompeo and T.R. Knight, as well as 27 "bridesmaids" in white dresses bearing info for the film. Heigl said her own bridesmaids wore something with a bit more color. "They were Oscar de la Renta - little, short cocktail dresses, cranberry red, very Christmas-y," she said.

Heigl told reporters she's wistful about her own De le Renta wedding dress, gushing, "I feel like I might just put it on to watch TV sometimes, because what else am I supposed to do with it?! It's so gorgeous. I never get to wear it again? That's sad." Of new husband Josh Kelley, she waxed poetic as well: "I look at him sometimes and think, 'Oh my god, you're mine.' That's pretty exciting." - Bekah Wright
