Kristen Bell revealed on Tuesday night's Conan that she was seven months pregnant when she filmed a sex scene for House of Lies.
Adam Brody was on the series playing Bell's boyfriend when the two shared intimate scenes together.
On Conan, Bell said that Brody "affectionately refers to our sex scenes as our threesomes because my belly was just on top of him."
Bell also revealed that she had to keep the sexual tension on the series while she was pregnant.
"That was kind of a big deal because it's a dark comedy, but it's also a very sexy show," Bell said. "We make a lot of jokes about sex, there's a lot of sexual storylines and I delivered two weeks after we wrapped."
"And there was a storyline in the second season when my character at work has a sex tape come out and she brings it into work and shows everybody, thinking 'let's just get it over with' and she's embarrassed, and no one cares," Bell continued. "But we had to shoot the sex tape and I was seven months pregnant at that time, and they were, like, fitting me in these negligees and I had this huge, just beer belly, just huge gut, and I was, you know, pretending to act in a sex tape and now I can forever look at my daughter and go 'Oh, you were present for that.'"

Bell gave birth to her daughter, Lincoln, in March 2013. The child's father is Bell's husband, Dax Shepard.
