It was a nice try, but it's looking like a no-go for the teen who asked supermodel Kate Upton to be his prom date.

Los Angeles high school senior Jake Davidson, 17, asked the Sports Illustrated swimsuit model to be his prom date via a YouTube video. In the clip, titled "Kate Upton, Will You Go to Prom with Me?" Davidson explains why Upton should be his date, including that they have a lot in common. For example, Upton poses in Sports Illustrated and Davidson reads it.

There was a glimmer of hope last week, when 20-year-old Upton tweeted Davidson, "How could I turn down that video! I'll check my schedule ;)" That hope has dimmed, however, with Upton now telling People magazine that it appears her dance card is too full to be Davidson's prom date.

"I'm not sure if I'll be able to go with him or not, due to my schedule," Upton said. "I want to, but I just don't know if I can make it work. But I really appreciated being asked; it made me feel really great!"

If you're going to let someone down gently, Upton certainly knows how, calling the video "so flattering."

"When a guy has a good sense of humor and confidence, that's attractive," she said.
