Celebrity maternity style: Sporty Olivia Wilde

Pregnant Cowboys & Aliens actress Olivia Wilde, 29, was spotted in this cute form-fitting maternity sweater with a humungous "O" (for Olivia?) on it, while out shopping yesterday at American Apparel in West Hollywood, California—but not before hitting a cafe for a much-needed hot bev.

Love her style... She paired the cool sweater with a relaxed tie-dye shirt, skinny jeans, her signature aviator shades and—no stilettos for Olivia!—awesome high-top sneakers.

Not surprisingly, Olivia makes pregnancy look easy. Maybe it's all the yoga and pilates—she's reportedly exercising almost daily to stay in shape. She was also spotted going to prenatal yoga class last week in a gorgeous ombre tee, yoga pants, a leather biker jacket and those comfy high-tops...

Olivia's getting set to star in a romantic comedy, Relanxious, costarring funny fiancé Jason Sudeikis, 38, who's been away shooting Horrible Bosses 2 (yes, a sequel...).
