Why Kristen Bell's Daughters Haven't Seen Frozen Yet

"She couldn't care less," the actress says of daughter Lincoln, 23 months

There may be only two little girls in the world who haven't seen Frozen.

Ironically, those two little girls belong to Kristen Bell, who voiced Princess Anna.

While promoting Oral-B and Crest's new line of Frozen-themed products, the actress revealed that her daughters, Lincoln, 23 months, and Delta, 11 weeks, haven't seen Walt Disney Animation's blockbuster. "[Lincoln] is not my biggest fan. She just doesn't know what I do for a living! She couldn't care less," she said. "[It] is extremely humbling to come home to someone who couldn't care less about what you do!"

Why did Bell and husband Dax Shepard decide to make their daughters wait to see the movie?

"The APA [American Psychological Association] recommends that you let kids watch TV when they're 2 and a half, so we're trying to follow that, which unfortunately is not realistic for all parents," Bell explained to Us Weekly, adding, "I understand, we're shooting for the moon.[It's for] their imagination, just so they don't become sedentary and used to zoning out to videos. But [Lincoln has] certainly seen videos. She loves the hell out of Snoopy! But we're trying. She certainly hasn't seen anything Frozen."

The Hit and Run co-stars' daughters will see it one day, of course.

"It's funny. I'm more excited as an audience member because of the sister themes. Because one day when I show it to both my girls together, it will have significance to them and their dynamic," Bell, 34, said. "I'm really excited about that because I think it really says something really special about sisters."

If Bell gets her wish, the princesses from Arendelle will enchant Lincoln and Delta.

"I hope I don't show them the movie and they both go, 'Eh,' the actress joked to People.

Echoing her earlier comments, the House of Lies star told the magazine, "My girls get along great, which I'm really grateful for. It will be exciting to show them Frozen one day because it's a story of sisters."

"When they both start watching TV," Bell said, "I think it will be a very special day in our household."
