Kate Uptons' Love Life Shyness

She has no problem prancing around in a bikini, but when it comes to romance, Kate Upton seems to clam up right away.

The 2012 Sports Illustrated Swimsuit Issue cover girl played it close to the vest while chatting with Ellen DeGeneres about New York Jets quarterback Mark Sanchez.

Kate began, “I did not have a Valentine’s Day date this year,” to which Ellen replied, “He’s cute. Don’t you think he’s cute?”

Upton blushed, "Yeah, he is cute. I've met him. My sister works for the Jets. And she's been working there for four years. So, I went to all the games."

"So, now you're dating him?" asked Ellen. Kate answered, "I met him briefly… I don't know what you're talking about."
