Why Kristen Bell's kids haven't seen 'Frozen'

"Frozen" may be the highest-grossing animated film in history, but there are still two kiddo's who haven't seen it.

Kristen Bell, who is the voice of one of the lead characters, Anna, told Us Weekly her daughters Lincoln and Delta are still out of the loop because they're too young to watch TV.

She said, "The APA 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 - I understand, we're shooting for the moon."

Lincoln is turning 2 in March and Delta still has quite a ways to go - Kristen and husband Dax Shepard her in December.

Kristen says she's in no rush to get her daughters into any part of the entertainment world - Lincoln still doesn't even know mommy is an actress!

She said, "She is not my biggest fan....She couldn't care less. [It] is extremely humbling to come home to someone who couldn't care less about what you do!"

She's also a little hesitant for another reason.

In a separate interview with People Mag, the actress said, "I hope I don't show them the movie and they both go, 'Eh.'"

The Internet was definitely supportive of the actress' parenting decision.

One Twitter user said, "She's got it right."

And HuffPost commenter Veronica Ramirez said, "I applaud her for that. I believe children are better off without watching TV until they are 3 years...Good job Kristen Bell!"

Kristen added in her interview with People that she's excited to show her daughters the film someday because it's a story about sisters.
