The Jingle Ball continues to hit a bunch of cities, as an assortment of A-list pop stars turned out at the Washington, D.C. edition of the radio show last night (Dec. 11), ranging from Justin Bieber to Ed Sheeran to Cher Lloyd to Austin Mahone to Enrique Iglesias.

Want to feel like you were there, enjoying the festivities? Check out the photos of the performances and the red carpet. With the exception of Lloyd, who looked ladylike in a pretty beige sheath, the pop stars were super casual on the carpet, dressed down in hoodies, jeans and sneakers. They were all performing so they didn't dress up too fancily before or after, and we can't say we blame them.

You can also enjoy some footage of The Biebs slowing things down with 'Fall,' where he strapped on an acoustic guitar. You can also soak in Iglesias as he belts out his smash hit 'Hero.'

See what we mean by making you feel like you were there? These photos and the video footage will do the trick.
