We’ll wash your back!

Sizzling supermodel Kate Upton gets ready for some steamy tub time after making a choice alteration to her tank top in a photo for the latest issue of Esquire magazine.

The 19-year-old former flame of Jet quarterback Mark Sanchez tells the magazine that, aside from NFL players, it’s the rough-and-tumble cowboy types who float her boat.

It makes sense, since Upton — also featured in Sports Illustrated’s new swimsuit issue — grew up riding horses in her native Florida and her grandfather was a Texas rodeo champion.
