She worked with Blake Lively and Cher while starring in a big Disney movie and is wed to a hunk, who is she?

This Hollywood beauty has a very long resume full of big TV shows and smash hit movies.

She has worked with Blake Lively on a famous series that was set in New York City.

And she has starred in movies with Mila Kunis, Cher and Christina Aguilera as well as Russell Brand and Vince Vaughn.

Her biggest hit to date was starring in a massive, household name Disney animated movie that spawned several ear-worm hit songs that eventually drove moms crazy.

This thespian is married to a showbiz actor and they have two kids together, though they never show the children's faces.

She is normally a blonde dish who rocks sexy dresses on the red carpet, but this week the actress was unrecognizable with dark hair in braids and casual clothing.

She is Kristen Bell.

The star was in Frozen with Idina Menzel and is married to Dax Shepard. Her films include Forgetting Sarah Marshall, Couples Retreat and Burlesque.

It was hard to tell it was her on Tuesday in Los Feliz, California.

Bell was seen leaving her Pilates class after a focused and intense workout, looking fresh and ready for the day.

She had on a white tank top that flashes her tummy, green sweatpants, black boots and a dark gray sweatshirt tied around her waist.

Bell was holding onto her cell phone which had a long beaded strap. 

This comes after Dax shared his reaction to his wife Kristen Bell's kissing scenes with her Nobody Wants This co-star Adam Brody.

Shepard, 49, joked that he 'didn't even know she could kiss like that' while talking about their sizzling, onscreen chemistry in the Netflix romantic comedy — which has been renewed for a second season.

While making an appearance at the New Yorker Festival on Saturday, he recalled recording his first podcast episode with his wife Bell, 44. 

When asked about the 'incredible chemistry' between them, he joked that it was 'not as good as her and Brody.' 

Then, he shared his reaction to watching the steamy and romantic scenes of Bell onscreen with Brody, 44. 

He began by saying he watched the show with his friend. 

'We watched that scene together, the kissing scene, which I'd argue is the very best kissing scene ever, ever put on film.'

He recalled: 'And my best friend, Aaron, from childhood, he goes, "Does she ever kiss you like that?" 

In response, Shepard said he answered: 'No, I didn't even know she could kiss like that.' 

Nobody Wants This is a hit romantic comedy, which follows Joanne, an agnostic sex podcaster portrayed by Bell, and Noah, a newly single rabbi played by Brody.

The unlikely pair fall in love, but their relationship becomes strained by their different religious beliefs and meddling families.

Earlier this month, the hit series, which is loosely based on creator Erin Foster's real-life love story with her husband, was renewed for a second season. 

Previously, Bell opened up about her and her co-star's steamy scenes and how supportive her husband has been.

'Even I can acknowledge watching it, like, "Whoa, that’s hot,"' Bell told E! News. 

She added: 'My husband said the same thing. Like, watching the first episode he was like, "Oh my God, I want you to kiss him so badly."'

Bell also acknowledged that even though her and Brody's scenes are sensual and passionate, their performances are calculated and logistical — emphasizing that it is all acting.

'I'm not trying to be reductive, but I think there's a math to it,' she explained. 

'You have two actors that know how to stare dopily into each other's eyes, and you have to have the confidence to expand that and really sit the anticipatory value before the kiss — which I think is really important.'

Nobody Wants This is now streaming on Netflix.
