Jets QB Mark Sanchez gets cozy with swimsuit model Kate Upton

Mark Sanchez is turning even more heads than usual these days, cozying up to sexy swimsuit model Kate Upton.

The Jets quarterback, 25, has been spotted frequenting 19-year-old Upton's Flatiron-area apartment since last month, according to a New York Post report.
His visits are usually after games or before practice, and he usually arrives in a chauffeur-driven car.

"They never come in together," a source told the Post about Sanchez's attempts to keep the relationship quiet from the media. "He's always five steps after her."

Sanchez has also tried to disguise himself by wearing a woolly cap.
Meanwhile, another source told the Post that Sanchez and Upton are "just friends."

In the past, Sanchez has been linked to "Sopranos" actress Jamie-Lynn Sigler and the now-single Hayden Panettiere.
