Hot mamma!

Jessica Simpson turned up the heat just in time for summer with an alluring Instagram snap that's making heads turn.

The 35-year-old fashion designer sported a black one-piece swimsuit complete with a plunging neckline from her namesake brand. Simpson donned loose waves and subtle makeup to complete the look, but her killer backside is really the star of this photo.

Of course, the mom-of-two was obviously very aware of this, as she included "#sunsoutbunsout" in the caption.

Another photo from her website displays the front of the sexy number -- including Simpson's ample bust popping out. The site currently shows the item as sold out, so those dying to replicate her sultry photo will unfortunately have to wait!

While the "With You" singer has put much of her efforts into her billion-dollar empire in recent years, she revealed big news to fans back in April.

"I'm back in the studio. It's been a very exciting time to rediscover music and I definitely have so much inspiration," the songstress told Huffington Post.

And what's better than Jessica Simpson in a hot swimsuit? New music from her that we can jam out too all summer long!
