However, sources say that the Sports Illustrated cover girl and the Jets QB are definitely romantically involved. An insider tells Us Weekly:

“They started hanging out about 7 months ago… He [Mark] is always at her apartment [and] has dropped off gifts and flowers for her.”

But the insider adds:

“It isn’t serious.”

Meanwhile, TMZ caught up with Kate and asked her if she was dating anyone. The model replied:

“What do you think?”

Then, when asked point-blank if she was seeing Mark Sanchez, Upton coyly answered:

“I don’t know! It’s whatever you think!”

Sounds like a “yes” to us. After all, if Kate really weren’t dating Mark, a simple “no” would be the more logical answer.

What do you think of Kate and Mark as a couple?
