JWOWW has been trying out a few different diets and working out non-stop, so it’s no surprise that she’s looking hotter than ever.

At an event for her new Ab Cuts line at GNC last night, our girl strutted her stuff in a teeny tiny black dress, looking sexy (yet still classy) and skinnier than ever!

Though she posed from many angles, this one of her standing sideways shows off her gorgeous curves, super-toned legs, and, let’s be honest — her fabulous ass. Her spiky pink platform heels gave her outfit a pop of color, and though her massive engagement ring stole the show, the loose waves in her hair and subtle makeup were also sheer perfection.

We think Jenni looks perfect in this dress, but what do you think? Is this her skinniest, sexiest look ever? Vote below!
