Kristen Bell and her co-star Adam Brody were not alone while filming their racy love scenes for their Showtime series "House of Lies."
Joining them was Bell's then-unborn daughter, Lincoln.
"I was seven months pregnant at the time and they were fitting me in these negligees and I just had this huge beer belly and I was, you know, pretending to act in a sex tape," the 33-year-old star told Conan O'Brien on Wednesday. "Now I can forever look at my daughter and say, 'Oh, you were present for that.'"
Bell added that Brody, who plays her boyfriend this season, jokingly referred to their TV sex scenes as "threesomes because my belly was just on top of him."
Of course, producers made sure to crop out Bell's growing tummy when the scenes aired.
Meanwhile, there was one guy who didn't seem to mind Bell's pregnancy body - her husband, Dax Shepard.
"He said he likes some meat on my bones … he phrased it as 'there's more of you to love,'" Bell told O'Brien.
"But then one time he did say, 'It feels like I'm cheating on you,'" Bell added. "And that I think was the ticket, because he felt like he was with a completely different woman."
Bell and Shepard's daughter turns 1 in March.
