Mila Kunis and Kristen Bell get way into the holidays....

ET's Cameron Mathison sat down with the two A Bad Moms Christmasactresses -- along with co-star Kathryn Hahn -- where they shared their mutual love of fun holiday decor.

"I love the holidays, so, I feel like I have just as much fun decorating for myself as I theoretically do for myself," Kunis admitted. "I love silly decorations, and I love things to be fun and not be classy."

"My whole house becomes an arts and crafts design project, and it's really just for me, 'cause I love everything to sparkle, like snow globes..." Bell concurred. "We have 35 Macy's Santa bears that are all over the couch."

That sounds like quite a commitment to holly jolly spirit!
