The candid pic comes just days after Bell's baby shower with famous friends like her “House of Lies” co-stars Ben Schwartz and Josh Lawson and friend Rachel Bilson.
"All my best girlfriends came to my baby shower," she tweeted Feb. 23, alongside a photo of herself with Ben and Josh. Writer Kelly Oxford even posted a silly pic of Kristen posing with breast pumps.
The 32-year-old “Veronica Mars” alum, who is expecting her first child with “Parenthood” star Dax Shepard, recently joked with Ellen DeGeneres about her labor day jitters.
"I feel like, when I arrive at the hospital, I want a glass of whiskey, I want the epidural in my back, and I want to get hit in the face with a baseball bat," she said. "Wake me up when it's over, because I've seen the videos -- and it looks terrifying."
