After Ellen shared her shock with Kate over how tiny her swimsuit looks on the cover, she got right to the point of getting the scoop on her rumored relationship.

"Your boyfriend, New York Jets quarter back Mark Sanchez. How does he feel about this?" she asked on The Ellen DeGeneres Show.

Kate played coy.

"I did not have a Valentine's date this year," she said, which is very surprising, but it didn't stop Ellen from her line of questioning.

"Okay, so he was busy," Ellen said. "So how does your boyfriend Mark Sanchez feel about all this? He must be proud, right?"

"Well, even if I had a boyfriend. I wouldn't ask how he felt about it," Kate said.

"He would just tell you, though. Has he told you? Your boyfriend Mark Sanchez?" Ellen asked while laughing. "I'm just guessing that it's him. Is it him?"

Kate did admit that Mark is "cute" and that her sister works for the Jets.

"I met him briefly," Kate said with a smile.

Ellen kept going, asking, "How long have you all been dating?"

Finally, Kate surrendered.

"I don't know what you're talking about."
