Kate Upton Doesn't Reveal Her Birthday Suit On Her Special Day, But She's Still Flaunting Curves In A Swimsuit!

Kate Upton NOT in a bikini???
We’re not sure how we feel about this.

Not that she doesn’t look super hot in this belted white one-piece and shiny silver pumps, but still.
We’re so used to her wearing a string bikini that barely keeps her assets from falling out that we can’t quite deal with this properly-fitting maillot, LOLz!
The supermodel, who turns 23 today, shared the pic on Instagram and wrote:

“You know just standing by a fake palm tree #vmag #sebastianfaena”

Guess that means a V Magazine spread is coming up! Yay!
Happy birthday, girl!
