Kate Upton's Sports Illustrated cover, first posted by TMZ.

You'd think Kate Upton would be the toast of the town right now. She's on the cover of the latest Sports Illustrated swimsuit issue, all but falling out of her bikini top, wearing what is quite possibly the lowest cut bottom ever. Across the country, 13-year-old teenage boys (and girls, and men, and women) are a-drool.

But for Victoria's Secret, she's like a day-old Big Mac. Though Upton's been featured in the lingerie catalog before, the woman who casts the annual Victoria's Secret Fashion Show said she'd never deign to let Upton walk that coveted runway. Sophia Neophitou told the New York Times that "we would never use" Upton because her look is "too obvious" to be featured in the high profile production.

"She's like a Page 3 girl," Neophitou said, referencing the busty, barely clad women featured in The Sun, a London tabloid. "She's like a footballer's wife, with the too-blond hair and that kind of face that anyone with enough money can go out and buy."

Upton's rep didn't immediately respond to ABCNews.com's requests for comment. But the 19-year-old, Michigan-born model and actress doesn't seem to care. Her Twitter feed is full of thank yous to her adoring fans, nearly 200,000 of which appear to find her "too-blond hair and that kind of face" entirely alluring.
