Jessica Simpson is no stranger to posting sizzling snaps on her Instagram account, and this weekend the singer took to her feed to share a super sexy photo of herself in a swimsuit. "Yacht Life #FBF," Simpson captioned the 'gram, which shows the star posing with her arms up on a boat. In the shot, the mother to daughter Maxwell, 3, and son Ace, 2, wears a cutout black monokini topped off with a sheer kimono-style robe.

And it looks like mom wasn't the only one hanging out in a swimsuit—Simpson also 'grammed a snap last week of her adorable look-alike tots having some fun in the pool. Aw!
