Kate Upton is getting cheeky with her latest Instagram post!

The 23-year-old model took to Instagram on Sunday to share a photo that highlights her bare butt (you're welcome!)

"Happy Sunday! #buttday #bruceweber #sundayfunday," the blond beauty wrote yesterday. The pic shows Upton modeling a semi-see through dress during a high fashion photo shoot with photographer Bruce Weber. Upton faces away from the camera, giving fans a perfect view of her naked bum underneath the gorgeous gown. Meanwhile, Upton's blond locks it up in an intricate hairdo.
