After discussing the SI cover, DeGeneres smoothly segues into her sneak attack. "And your boyfriend, New York Jets quarterback Mark Sanchez, how does he feel about this?"
Upton, 19, who hasn't officially acknowledged that the two are dating, laughs nervously and offers up a silly non sequitur. "Um, I did not have a Valentine's Day date this year," she replies.
"OK, so he was busy," says DeGeneres, undeterred. "So how does your boyfriend Mark Sanchez feel about all this whole Sports Illustrated cover thing? He must be proud, right?"
Several awkward exchanges continue from there, with DeGeneres trying to hold in laughter and Upton trying to sound coy, but looking like a deer caught in headlights. Eventually the blonde bombshell admits that she's met him. "My sister works for the Jets," she says. "And she's been working there for four years. So, I went to all the games."
"So, now you're dating him?" asked DeGeneres, which led Upton to finally admit that she's met him "briefly."
Thankfully, DeGeneres refrains from mentioning the news reports about Sanchez's many visits to her New York City apartment. Instead, she skips right to the more pertinent question of how long they've been dating. Fully flummoxed, Upton laughs and says, "I don't know what you're talking about."
"All right," said DeGeneres, and turns to the audience. "She's dating Mark Sanchez."
