The who’s who of Hollywood hit the Sundance Film Festival in Park City, Utah this week, where the stars traded tank tops and flip flops for hooded parkas and snow boots. And we were there!

This year, the film fest, best known for awesome parties, major swag suites, and, oh yeah, movie screenings, was heavily populated by our favorite kind of stars — mommy ones! Here’s what our fave celeb moms were up to:

Naomi Watts
Film: Two Mothers
The mom of two sons with partner and fellow actor Liev Schreiber left all three boys at home so she could focus on work during the festival.

Kristen Bell
Film: The Lifeguard
The pregnant mom-to-be came without fiancé Dax Shepard, who was in L.A., but said she was feeling good. Kristen was happy to check out the gifting suites for swag, and smart enough to plan ahead by asking a friend to help her carry her stuff out so she wouldn’t be loaded down.

Alicia Keys and Jennifer Hudson
Film: The Inevitable Defeat of Mister & Pete
Both incredible singers (and moms) were on hand to promote Keys’ movie, The Inevitable Defeat of Mister & Pete, which she executive produced and Jennifer starred in. “I love the fact that I’m here, not necessarily to sing a son, but to present an incredible film,” Keys told Vibe.

Nicole Kidman
Film: Stoker
Nicole hit the festival solo (hubby Keith Urban was tied up with American Idol), but said she had fun anyway, especially at the very exclusive CAA party on Sunday night.

Julianne Moore
Film: Don Jon’s Addiction
The beautiful actress made the film fest a family affair by bringing along her husband, Bart Freundlich, and kids, daughter Liv and son Caleb.
