Kristen Bell's husband prefers her to go makeup-free.

The 'Frozen' star has revealed her hubby Dax Shepard - with whom she has Lincoln, two and three-month-old Delta - often encourages her to go bare faced, while her kids simply advise her to smile as much as possible,

She explained: ''[He said] stop wearing makeup, which is obviously very flattering! I think he prefers me makeup-free.

''I think what I've learned about beauty from children is number one, you're always more beautiful when you're laughing, and number two, a little bit of sunscreen can go a long way. Your skin will simply look more youthful if you commit to wearing sunscreen and protecting yourself from UV rays.''

The blonde beauty added she feels at her most attractive when she's around her family.

She said: ''I honestly feel most beautiful when I'm in a snuggle pile with them, and also when there's no mirrors around. Because I think it's such a trap to think that beauty is all visual, and the more you focus on it being a feeling, the happier you'll become. I truly believe that.''

However, Kristen, 34, still enjoys getting dolled up for red carpet appearances and treats herself to a pedicure every now and again.

She told PEOPLE: ''I would love to say I did a gorgeous smoky eye, but I just don't have the time. And I think that makeup is especially about balance, and I find that all I have to do is a swipe of mascara if I do a bold lip and it tends to be a quicker makeup process.

''If I have the time, I get a pedicure. I usually stick in the red families; I like to stay bold for my feet. I think feet are not innately gorgeous, so they deserve a lot of pizzazz. [That's

why] I usually stick with a pretty bright red.''
