The expecting star showed off her baby bump on the set of "House of Lies" on Tuesday in Los Angeles.
The blonde beauty looked ready to pop as she made her way around the set. Rocking a blue blazer, a black T-shirt and black jeans, Bell didn't even look pregnant when photographed from the back ... but, from the front, it was a whole different story!
The "Veronica Mars" star and hubby Dax Shepard announced they were expecting their second child together back in June. "The whole family is beyond excited," a spokesperson for the couple told ET at the time.
The actors already share an adorable daughter together, Lincoln, who they welcomed in March 2013 -- and we're sure their little cutie is beyond excited to have a sibling any day now!
