Mark Sanchez Girlfriend: Is He Dating Kate Upton?

Jets quarterback Mark Sanchez has been linked with a host of women in the past, but the latest rumor that he is seeing Sports Illustrated swimsuit model Kate Upton seems to top them all.

The New York Post's Page Six reported on Wednesday that the Jets' popular quarterback had been seen multiple times visiting Upton's Flatiron apartment in New York City. The Post reports that he has been seen multiple times since November, including a few after-midnight visits.

They never come in together. He's always five steps after her, a source told the Post, while also noting that Sanchez often hides under a woolly hat

The handsome Sanchez has been linked to a few different celebrities since coming to New York to play with the Jets. He's previously dated actresses Hayden Panettiere and Jamie-Lynn Sigler, sportscaster Lindsay McCormick, as well as being spotted with numerous unknown beauties in New York clubs and restaurants.

Upton, 19, has previously been linked to rapper Kanye West, but her dating life has mostly been under the radar. In addition to her appearance in the Sports Illustrated magazine, she also works as a Victoria's Secret model.

Representatives for both denied to comment to the Post, but there is a natural connection between the two. Upton's older sister Christie works as a manager of client relations for the Jets and has taken Kate to a few Jets games this season.

One source insisted to the tabloid that the two are just friends, but the multiple late-night visits seem to suggest otherwise.

Sanchez is currently preparing for an extremely important game on Christmas Eve against local rival New York Giants. A loss would likely knock the Jets out of a potential playoff spot.
