Mark Sanchez Girlfriend Kate Upton?

Mark Sanchez, quarterback of the New York Jets, has been linked to Sports Illustrated Model, Kate Upton.

According to Wednesday’s issue of the New York Post: “He’s been spotted several times at the voluptuous blonde’s pad since November, usually after games or before practices - sometimes as late as midnight.”

Upton’s sister works as a manager of client relations for the Jets, and it is possible that Upton met Sanchez attending one of the games with her sister.

The 19-year-old also models for Victoria’s Secret and has appeared in Esquire and Guess.

The New York Post reported that the two never come in together but that Sanchez often comes to Upton’s building before or after games.

“Sanchez was even seen in Upton’s building lobby carrying gifts for her after he attended 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,” the New York Post reported.

Mark Sanchez has also dated celebrities like Hayden Panettiere and Jamie-Lynn Sigler. Earlier in 2011, he was linked to a 17-year-old girl in Connecticut who reported to that she “hooked-up” with him at a club.

The Jets are currently fighting for playoffs and will play the New York Giants this Christmas Eve. The game will be important because a loss for the Jets could mean losing a playoff spot.
