Kate Upton has sky rocketed herself to fame by gracing the cover of this year's Sports Illustrated Swimsuit Issue, but now we of course have to know -- who is she dating!? The recent rumors have linked Upton to New York Jets quarterback Mark Sanchez!

During an interview on The Ellen DeGeneres Show (airing Thursday), Upton was quizzed about her love life, and although she was pretty vague in her responses, the talk show host has come to a conclusion regarding her relationship status. Ellen started the questioning asking what Upton's boyfriend (specifically naming Sanchez) thought of her SI cover, to which the model responded, "I did not have a Valentine's date this year." Huh!? Watch the vid to check out the rest!

Of course, being Ellen DeGeneres, the funny lady pushed the issue, continuing to refer to Sanchez as Upton's man. Upton gave responses like, "Well, even if I had a boyfriend I wouldn't ask how he felt about it!" HOWEVER, although she failed to admit she was in a relationship with the football player, Upton did say she has met him a few times through her sister who works for the Jets -- and she thinks he's cute!

Still, at the end of the interview, Ellen concluded, "She's dating Mark Sanchez!" Hmm...it seems to me like Upton may be telling the truth about her relationship status, but that doesn't mean she has no interest in Mark, right?! Hint, Hint, Sanchez!

Do you think Kate Upton & Mark Sanchez are dating?!
