Is N.Y. Jets' Mark Sanchez Dating Model Kate Upton?

It looks like New York Jets quarterback Mark Sanchez, 25, may be the most recent sports hero to shack up with a beautiful model, in this case Victoria's Secret and Sports Illustrated swimsuit model Kate Upton, 19, who has previously been romantically linked to musician Kanye West.

Sanchez has been seen making late-night visits to Upton's apartment in Manhattan's Flatiron District since November, sometimes carrying bags of gifts. "They never come in together," a source told Page Six. "He's always five steps after her."

Upton, who is from Michigan, has also been seen attending some Jets games. It just so happens that her sister, Christie Upton, manages client relations for the team.

Sanchez has previously dated The Sopranos' Jamie-Lynn Sigler and Heroes Hayden Panettiere, not to mention allegedly pursuing 17-year-old Eliza Kruger earlier this year.

If you want to see Upton somewhere other than the sidelines of a Jets game, take heart. She had a small role in this year's Tower Heist with Eddie Murphy and Ben Stiller, and will also appear in the upcoming film version of The Three Stooges alongside Larry David, Sean Hayes and Jane Lynch. GQ recently named her "Body of the Year."
