Taking her growing baby bump out for some late night fun, Kristen Bell made a stop by "The Tonight Show with Jay Leno" on Friday (January 11).

The "Forgetting Sarah Marshall" actress looked beautiful in a navy knee-length dress that accented her "400 pounds months" big belly.

Dishing on how she and her hubby Dax Shepard have prepared for the little one in "very different ways," Kristen said, "I have done like 'oh that looks cute for a bed sheet' and he has been feverishly searching the internet for a '96 Caprice station wagon with a LT1 Corvette motor because it's very important to him that our family car burns rubber."

GossipCenter first reported that the Hollywood pair had a bun in the oven back in November and it is expected that she will give birth in April or May.
