Dax Sheperd is definitely a "free spirit."
Kristen Bell appeared on Conan on Tuesday, where the host brought up her hubby's jokes the last time he stopped by the TBS show. Shepard jokingly suggested that he and Conan O'Brien do a "wife swap" and switch it up.
"I don't want to hurt your feelings, but you're not the first person he's tried to get us to swing with," Bell said. "He's a very free spirit, you know. ... Also a horn dog, but around my parents, we say free spirit."
"We're not actually swinging with anyone," she clarified. "He just loves people. He loves the human frame and he constantly suggests at different dinner parties that we 'hang out' and 'really get to know each other.'"
Bell, 36, did admit that there's one couple they're "so in love with" -- her Veronica Mars co-star, Ryan Hansen, and his wife, Amy.
"We've decided that our couple will marry their couple," she said. "Since we got married, we call each other super spouses, and we are the first-ever four-way couple."
Though all jokes aside, Bell couldn't be more in love with her husband. The Good Place star sweetly defended the 41-year-old actor when O'Brien poked fun at the overalls he was wearing during his last appearance.
"First of all, he can wear anything he wants, OK? He's that adorable and charming, and he has his own sense of style," Bell said. "And don't you think it's great that he doesn't just fall in line with like, 'I guess I'm going to wear a suit, or a sweater vest, or whatever everybody else is doing?'"
Bell also explained that there's a very good reason Shepard needs a pair of overalls.
"He's also very manly!" she gushed. "He works on all the machines at her house. If anything breaks, he'll be able to fix it. So, he's got to have overalls, you know?"
ET spoke to Bell earlier this month at the Emmys, when she got real about balancing acting and parenting her two daughters with Shepard -- 3-year-old Lincoln and 1-year-old Delta.
"Only one of us works at a time," Bell told ET exclusively. "We have a lot of great people that are our support system and we bring our kids everywhere -- my babies come to work every day, I have the luxury of doing that. We're very mindful about taking jobs that will not take us away from them too much."
