Victoria’s Secret and Sports Illustrated swimsuit model Kate Upton and New York Jets quarterback Mark Sanchez are an item, according to the New York Post.

Sanchez has been paying frequent late-night visits to her NYC apartment, having been spotted several times at the voluptuous blonde’s pad since November.

Mark is 25 years old. Kate Upton is 19. Nineteen! Just barely passing the "half your age plus seven" test, that's a step up from his old GF Eliza Kruger, 17.

Sanchez was seen in the lobby of the building where Kate Upton (who's also been linked to Kanye) lives, carrying gifts for her after a charity event early last month.

On another occasion, Sanchez was spotted coming into the building with bags a minute or two after Upton arrived. They've also been seen at his place of work.

Upton has also attended some Jets games as her sister, Christie Upton, is a manager of client relations for the team and works closely with Mark Sanchez.

Another source insists that Upton and Sanchez are “just friends.”

The Jets QB has also been linked to actresses Jamie-Lynn Sigler and Hayden Panettiere, who’s now dating his teammate Scotty McKnight, in recent years.
