Actress Kristen Bell has revealed she filmed a sex tape scene for her TV show House Of Lies while pregnant with her daughter. The saucy episode recently aired and now Bell confirms she had to hide her baby bump in the scenes. She explains, "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 just had this huge beer belly, this huge gut, and I was you know, pretending to act in a sex tape." She jokes, "Now I can forever look at my daughter and say, 'Oh, you were present for that!' "My boyfriend this season was Adam Brody, and he affectionately refers to our sex scenes as our 'threesomes' because my belly was just on top of him." Bell and actor husband Dax Shepard welcomed their first child, daughter Lincoln, last March (13).
