Jessica Simpson has never looked better!

The business mogul took to Instagram to show off her killer beach bod in a sexy swimsuit from her Spring collection. In the shot, the pop star put her booty on display in a black one-piece, which features jewel-tone patterned bands at the waist and a low back.

“Get your suit on! Never-been-seen footage from my Spring ’16 photoshoot is on the website!” she teased, adding the hashtag: “#sunsoutbunsout.”
