Kristen Bell rowed with Dax Shepard because she wanted to show off her boobs in 'CHiPS'.
Dax Shepard and Kristen Bell
The blonde beauty - who has daughters Lincoln, three, and two-year-old Delta with her husband - was directed by and starred alongside her spouse in the new action comedy, and the only time they didn't get along on set was when he was unhappy with her request to alter her costume to show off her "big, beautiful balloons".
She said: "It's funny, the only disagreement we had the whole time was when I wore this bathing suit in the movie - I play this vapid, rude, estranged wife -- and I wanted to unzip my bathing suit more to give her a really aggressive boob job and have her be a Beverly Hills housewife, and he wanted me to zip it up.
"He was like, 'It's pulling focus!'
"I had to ask! I get them once in my life, because I was breastfeeding! Let me have big boobs -- big, beautiful balloons."
Despite the disagreement, Kristen joked she was given "special treatment" on the set because she's married to the director.
She quipped to AOL: "We're always kissing no matter where we are. PDA is going to happen, special treatment is going to happen and everyone is just going to have to get hip to it, you know what I mean?"
And the 36-year-old actress admitted she is more "nervous" about the response to 'CHiPS' than she usually is about her movies because of her and Dax's relationship.
She admitted: "Normally, I'm pretty calm, but I'm more excited and nervous for this one because it's my partner's baby.
"I saw him from the moment he decided to take this on to the few months he was writing it to the few months he was prepping it to shooting it, and I'm just so happy for him
"I'm just excited that people will finally get to see a little sliver of his brain!"
