Mark Sanchez has found himself to be quite a catch with the ladies.

If you will we recall last year he was rumored to be dating Hayden Panettiere, before they both admitted they were just old-friends...

Now it looks as though Mark might be dating Sports Illustrated Swimsuit cover model Kate Upton.

Rumors have been spreading like wildfire ... Mark and Kate are an item -- but we asked the buxom Victoria's Secret angel straight up ... are you single ... and she played coy, replying, "What do you think?"

We pressed a little more ... asking if Mark was the mystery man -- Kate hedged, responding, "I don't know!"

As for the real truth -- Kate tells us, "It's whatever you think!"

We this YES!! Let's face it, if you deny then you say, "we're just friends." She didn't say that!
