Time to celebrate Bell's bump! After announcing in November that she's expecting her first child with fiance Dax Shepard, Kristen Bell got together with all her close friends on Saturday, Feb. 23 for a baby shower.

"All my best girlfriends came to my baby shower," Bell, 32, tweeted with a photo of herself posing between House of Lies costars Ben Schwartz and Josh Lawson.

Also in attendance at the shower were Bell's good friend and actress Rachel Bilson and writer Kelly Oxford. Bilson, 31, was photographed carrying a stuffed animal while entering the party at a private residence in Los Feliz, Calif. 

Oxford tweeted a photo of pregnant Bell unwrapping a gift of breast pumps. "At Kristen Bell's baby shower and she's totally trying to get me to put the next baby in her," the writer joked.

In the funny photo, Bell made a kissy face to the camera while posing with the pumps. The actress also shows off her growing baby bump in Isabella Oliver's Tilda Print Maternity Maxi Dress, which retails for $465. 

Though it looks like Bell was unwrapping a pink present and Bilson was photographed carrying one to the party, the mom-to-be and Shepard, 38, are keeping the gender of their baby under wraps.

During an appearance on The Ellen DeGeneres Show in January, Bell said her fiance was excited about "all the off-roading he'll have in this tiny partner."

Does that mean they're having a baby boy?

"Maybe? Do you have to be a boy to off-road? Absolutely not!" she said. "I think [Dax]'s going to force [the baby] . . . to off-road."
