Coco Rocha Talks Pregnancy, Her New Book and Why She's Not a Party Animal

Stunner announced earlier this month she was expecting her first child with husband James Conran

Supermodel Coco Rocha knows a thing or two about posing.

And now she's really showing off her abilities in Study of Pose, a new 2,032-page book showcasing Rocha in 1,000 different poses shot by photographer Steven Sebring.

Rocha, 26, appears in nothing but a white leotard.

"We thought it would be a lot more historical for the book itself and that you wouldn't know what period it came from, it could have been from the early '20s to now, it really doesn't have a timestamp on it," Rocha said of her minimalist look. "It wasn't about the styling because style goes in and out so when you look at this book I didn't want you to go, 'Oh, that definitely was shot in the '80s.' It was just really almost a science of the art of the body and it was nice to just see the figure and the lines of the body so we thought that having it in a leotard was just kind of the perfect classical thing to do."

The poses were shot on a contraption with 100 cameras that Rocha and Sebring call "The Rig." "Each pose is shot with a hundred cameras and a hundred thousand photos so digitally it's a very beautiful application," Rocha said.

If she were wearing a leotard today, Rocha's silhouette would be a lot different. Earlier this month, she announced that she was pregnant her first child with husband James Conran. "We're definitely going to be slowing down a bit because we have a baby on the way," Rocha said. "I'm excited for the next chapter in my life for sure."

They're picking out baby names, but won't make a final decision "until we meet this little person."

Rocha is a rarity in the fashion world because she's not only open about being a devout Jehovah's Witness, but she also refuses to take on jobs that are sexual in nature because of her religious beliefs. "People know if we get Coco, this is what we get, a model who can pose her life away," Rocha said. "That's why I work extra hard. I give you 110 percent."

It's no surprise that Rocha hasn't fallen to the self-destructive partying side of the fashion world.

"I just don't know how anyone has time to do all that," she said. "You know you're working so hard and then at the end of the day I don't want to go out partying. I want to go home and enjoy hanging out with my husband and watch some great Netflix in my pajamas. The last thing I want to do is go out and hang out with people I've been hanging out with all day. I go to events, dinners and functions and that's definitely part of work for me and sometimes fun, but I love to be that average girl and go home and just enjoy being at home."
