Kristen Bell wants naked yoga

Kristen Bell wants to do naked yoga.

The 'Frozen' actress - who has daughters Lincoln, five, and Delta, three, with husband Dax Shepard - discovered her neighbour was running classes via a local app and joked she's taken a particular interest in his advertisements.

She told talk show host Ellen DeGeneres: "I've never done naked yoga but I've actually wanted to.

"A dude from my area is advertising his naked yoga class and he always incorporates a picture which I find very odd. He's always doing an inversion.

"When men are doing inversions, it causes you to stare at the picture for a minute to see what's going on."

The 38-year-old star's 'Momsplaining With Kristen Bell' series on Ellen's EllenTube channel is returning for a second season and Kristen loves to show off the "messy and gross" aspects of having children.

She said: "It's basically momsplaining through my lens, through the lens of a mother. How moms see things.

"It's not your typical way because the way I see things, they're dirty and they're messy and they're gross and you love them and you hate them and it's all those things. It's also very funny."

And Kristen was delighted she got to witness a live birth from the "splash zone" after Martha Trujillo agreed she could be in the delivery room with her.

She said: "I had said to the 'Momsplaining' team, I said, 'I want a delivery. I want to be in the delivery room.' And they kind of looked at me like, 'OK that's very intimate.' And I was like, 'Just try to make it happen. It's Hollywood!' "

A clip from the upcoming series showed Kristen visiting newborn twins and their mother Kimberly Patel, who the 'Bad Moms' star gifted with an ice park for her vagina.

She then told the new parent all the names she has for her own intimate area, including "Who-ha, Honey pot, Baby cave, Man eater."

On Ellen's show, the host and her guest reduced both Kimberly and Martha to tears when they presented them with $10,000 per child for their college education.
