A new round of reports is circulating suggesting that Sports Illustrated Swimsuit Editon cover girl Kate Upton and New York Jets player Mark Sanchez are dating.

Back in December, the New York Post reported that Mark was visiting Kate’s apartment — a lot. Now, buzz of their purported relationship is raging again.

TMZ’s cameras caught up with Kate this week, and asked what’s up. Her response? “I don’t know,” she said. “It’s whatever you think!”

Meanwhile, a source tells Us Weekly, “”She says they are friends…They started hanging out about 7 months ago. He is always at her apartment [and] has dropped off gifts and flowers for her . . . It isn’t serious.”
The source says the pair met through her old sister, who works for the Jets.
