Derek Hough is baring it all -- sort of.

The "World of Dance" judge took to Instagram this week to share two nude photos of himself and his girlfriend, Hayley Erbert, taking showers during a getaway in Big Sur, California.

"Morning view," he captioned both of the black-and-white pictures, which show Hough and Erbert from behind separately standing while taking an outdoor shower while enjoying the view from their room. The couple presumably took the photos of one another.

Erbert also shared a cheeky snap of the couple that shows them naked from behind, with two peach emojis covering their derrieres.

"#InHonorOfTheFullMoon," she captioned the shot, which you can see in the video above.
