The 36-year-old actress -- who stars in NBC's freshman series The Good Place, debuting Monday -- looked stunning as she hit the Emmys red carpet on Sunday, arriving solo while husband Dax Shepard stayed home to care for their two children.
"He doesn't like dressing up, so he's much more comfortable in his cut-off jeans and his tank top at home with the kids," she confessed to ET's Kevin Frazier.
Bell adorably documented her pre-show glam session on Instagram, from her fresh-faced skin treatments to a head full of rollers and clips.
"I got ready at a room around the corner actually, my kids like to pick sequins off of things and this would have been very dangerous," Bell said of her gorgeous Zuhair Murad gown, featuring a plunging neckline and full, flowing skirt.
"I love Zuhair Murad, I think he's such a talented designer and I wanted to do something more whimsical and this was perfect," she said of the dress, joking that it would have wound up in "a giant yarn ball" if her kids had been allowed near it.
Just last week, Bell took to social media to share sweet snaps from a family trip to Michigan. Now, with fall TV season upon us and The Good Place debuting on Monday, Bell got real about how she and Shepard balance career and family life with their daughters, Lincoln, 3, and Delta, 21 months.
"Only one of us works at a time," Bell said. "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."
