This is not, of course, the first time Ms. Hudgens has proven she knows how to get down. In March, the singer-actress dropped by The Tonight Show, and after telling Jay Leno about a dance-off with Madonna's crew, she demonstrated her own twerktastic moves.

"When it comes to my dancing," she said, "it's like—I hate to admit it—but its kind of like a lot of booty-popping involved."

Hmmm. Not bad, but Miley still keeps her title as the Queen of Twerk—for now, at least.
