She’s due in less than a month, and Shiri Appleby sure looks ready to pop!

The 34-year-old actress shared a photo of her bare baby bump on Instagram Friday, tweeting ” T minus 20 days.”

Appleby, who has guest-starred in Girls (but is probably best known for her role on Roswell), is expecting her first child with fiance Jon Shook, a chef at L.A.’s Animal restaurant.

The couple got engaged in July 2012 on a romantic getaway to Ventotene, Italy.

“One second you’re having lunch, the next you have a ring on your finger!” the actress told Us Weekly.

So is the nursery going to be filled with pink or blue? That remains to be seen as the pair have decided to keep the gender of the baby a surprise.

“He really wanted to do it and it sounded like fun,” said Appleby.  “It’s really made the whole pregnancy a heightened excitement because you just don’t know what it’s going to be!”
