Britney Spears’ Video for ‘Till the World Ends’ Debuts

On Wednesday, Britney Spears debuted her new music video for her latest single “Till the World Ends.” The song, written by Ke$ha is the second single off her “Femme Fatale” album.

If you didn’t know, in closeup shots, Britney wears Ugg boots instead of heels. “A girls’ got to go for the comfort when she can,” she told The Daily Mail. Plus, Ugg boots have really good support for cankles.

Sidenote: She must have un-flexed her thighs  at the beginning of the video because at one point there was some jiggle. It was like her legs were made of jelly. Mmm, jelly.
