We’re going a bit crazy over the idea that Olivia Wilde is knocked up and currently has a little Jason Sudeikis bun in the oven. Now, the Hollywood siren is stepping out to show off her baby bump... and she’s making it pretty hard to miss.

The 29-year-old  Tron: Legacy star the red carpet at the premiere of her new movie, Her, on December 12, and Olivia made sure that her growing baby belly took center stage.

The actress wore a skintight blue dress by David Koma. Not only did the fabric cling to her growing belly, but the dress featured crystal embellishments on the neckline and the waist, the latter of which also served to showcase her bump.

Thursday marked the first time Olivia had shown off her baby bump. She made an early-morning appearance in Beverly Hills to announce the 71st Annual Golden Globe Award nominations, but kept her bump more or less covered in a more conservative black ensemble.

This will be Olivia’s first child. She and Saturday Night Live vet Jason have been linked since December 2011, and got engaged in January 2013. The couple confirmed Liv’s pregnancy in October, and their little bundle of joy is due sometime next year.
