Kristen Bell thinks being a good person is the "quickest way to feel beautiful".
The 'Frozen' star believes beauty comes from within and feels self-esteem is the most important part when it comes to feeling good about yourself.
She told People Style: "The beauty lesson that is paramount, is your beauty comes from inside, not out. You can make yourself look however you want to look but you will not feel beautiful until you have self-esteem, and you will not get self-esteem until you participate in estimable acts.
"So being a good person is the quickest way to feel beautiful. There's no getting around it ... There are a thousand quick fixes to beauty, but really, it's your inside heart. That's what makes you feel pretty."
And the 36-year-old actress' husband Dax Shepard - with whom she shares daughters Lincoln, three, and Delta, two - previously admitted he was suspicious of Kristen's "unbridled happiness" when they first met.
He said: "When I met her and her friends, I was suspicious of their unbridled happiness. I thought, 'Something stinks here; they're in a cult.'"
And Dax has admitted there were "hurdles" in the couple's marriage but feels they have come out of it stronger.
He added: "There were hurdles, things she didn't trust about me, things I didn't trust about her. I just kept going back to, 'This person has the thing I want, and I have to figure out how we can exist peacefully.' So we started [seeing a therapist together] right away."
Whilst Kristen shared: "I need to remind people that you don't just find one person and then it's all peaches and cream for the rest of your life. Marriage and a relationship is hard work, and it's a lot of compromise. But if you compromise a lot, it's worth it."
