Olivia Wilde sunglasses pregnant baby bump spin class west hollywood spandex tights beautiful

Hot mama!

Olivia Wilde went to spin class in West Hollywood on Wednesday afternoon, and the 29-year-old starlet showed off her baby bump in a pair of workout pants and a tie dye top.

Olivia also gave us a peek at her growing belly at the Golden Globes over the weekend in a skintight green Gucci gown, and she tweeted the other day, "Hahaaaa I just heard someone say I looked like a giant, walking pickle last night at the Globes. As a pickle enthusiast, I thank you." The same day Olivia confirmed that she and Jason Sudeikis are expecting a baby boy ... wonder if they've thought of names yet?
