Jessica Simpson took to Instagram last night, May 26, to proudly show off her bathing suit bod -- and she looks incredible.

Simpson, a Weight Watchers spokeswoman who has opened up in the past about her struggle to lose her post-pregnancy weight, confidently flaunted her flattering figure in a colorful cutout swimsuit that showed off her sculpted legs, toned physique and tanned cleavage.

"If I'm in a bathing suit I should pose proudly," Simpson captioned one of the shots -- and we couldn't agree more. Not only has she worked hard for her body, we love that the singer isn't afraid to work her figure in front of the camera, showing those weight bullies who is boss.

In addition to her enviable curves, we also love that she's posing with her husband's golf club while rocking some of the highest peep-toe espadrilles we've ever seen. Simpson totally has the hot mama thing going for her, complete with white picket fence in the background. We love it!

But of course, the best accessory that Simpson is donning in the pics is not just the cutout bathing suit or the killer heels -- it's her unwavering confidence, which sends an empowering message to women everywhere to be proud of their bodies.
