The YouTube videos show Selena and her body double during different takes of the bold promo, in which the 19-year-old performs a pop-inspired rap song called 'Congratulations to Me.'
"It is funny, the whole thing of it ... me being always sweet and the contrast of this is kind of different," the singer says in the video. "It's the first time for me to kind of let loose and just be silly, and it's kind of awesome."
Selena also says she styled herself on the shoot, drawing inspiration from guys who rock low-slung jeans and exposed boxers. We have a hunch Justin Bieber's look played a part in her choices, too.
Check out the two behind-the-scenes videos below, and get ready for Selena to host the 2011 MTV EMAs on Sunday, November 6 from Belfast, Northern Ireland.
