Olivia Wilde The Grove

Olivia Wilde and a pal stopped by the Grove in Los Angeles to do a little Christmas shopping on Thursday evening, and the pregnant actress covered up her baby bump with a baggy sweater and jeans. Just the other day she showed off her growing belly in a form-fitting dress at the premiere of Her, but it seems like she likes to mix it up when it comes to her maternity style.

Olivia appeared on The Tonight Show With Jay Leno on Tuesday, and she chatted about how people have been tiptoeing around her pregnancy news. "That's the worst thing in the world -- when you congratulate a non-pregnant woman on her pregnancy," Olivia told Jay. "I find that people will go to such great lengths to not mention it ... Even when you are clearly -- like, I feel like I'm clearly pregnant -- people will be like, 'Hey, would you like a glass of whiskey? Would you like to get on this roller coaster?' And I go, 'Oh, well, I'm actually pregnant.' And they go, 'What?!' Unless someone's watching you give birth, I don't think they want to make the wrong call."

Her baby bump isn't THAT big, but we see her point. So is it a boy or a girl? "It's human," she joked. "[Jason Sudeikis and I] feel good about that."
