Teyana Taylor: If You Wanna Eat Twinkies Dance Your Ass Off!

Teyana Taylor's killer body is not only a tasty treat ... it's filled with them.

We caught the "Fade" dancer leaving Ace of Diamonds where you'd think she showed the girls there how to get down. But check out the vid ... instead we learn she's got a major sweet tooth.

And get this ... her fiance, NBA star Iman Shumpert, has his own plans after watching her in Kanye's vid.
