Holy woof! Chrissy Teigen is known for being candid about her sex life with husband, John Legend, but she just took it to a whole new position.

The model and cook book author tells Marie Claire magazine why she's taken one thing off the menu in the bedroom...

She tells the magazine "we are never doing doggy style again," after her husband informed her that during the act he's able to see an extremely intimate body part.

Until then, Chrissy was convinced that she'd never exposed that before, and she'd prefer if she didn't.

Chrissy has always been very open about her intimacy, and we suppose if you expect her to not share the gritty details, you're barking up the wrong tree.
