'Mark Sanchez is cute': Kate Upton plays coy and states the obvious about her rumoured boyfriend on the Ellen Show



She's confident enough to flaunt her body on the cover of Sports Illustrated, but Kate Upton is far cagier when it comes to talking about her love life.

The 19-year-old swimwear model did her best to avoid answering Ellen DeGeneres' questions when she appeared as a guest on the Ellen Show today.



Though she looked confident and sultry in a form-fitting white dress, she seemed a bit abashed as she deflected the comedienne's inquisition.

What do you mean you don't know? Kate Upton won't admit to dating Jets quarterback Mark Sanchez

The 54-year-old host immediately started in on her line of questioning, wondering what Sanchez thought of her SI cover.



'Your boyfriend, New York Jets quarterback Mark Sanchez. How does he feel about this?' she asked.



As she got increasingly uncomfortable and started tittering nervously, Upton responded: 'Even if I had a boyfriend, I wouldn't ask how he felt about it.'

DeGeneres didn't stop her grilling there though: she kept on pressing.



'Have you met [Sanchez] before?' she asked.



The blonde bombshell responded in the affirmative. 'I met him. My sister works for the Jets. She's been working there for four years so I went to all the games.'



The best Ellen could do was get Upton to reveal that she spent Valentine's Day alone - and that she thought the NFL star was attractive.

She and the athlete have never confirmed their romance, though a source tells Us Weekly that the two aren't in a serious relationship.



The insider said: 'They started hanging out about seven months ago. He's always at her apartment [and] has dropped off gifts and flowers for her. It isn't serious.'
