Carly Rae Jepsen: New Year's Rockin' Eve Performer!

Carly Rae Jepsen dances it up with the crowd while performing at Madison Square Garden in New York City on Wednesday night (November 28).

The 27-year-old musician and Cosmo cover girl was just announced as one of the performers for the 2012 New Year’s Rockin Eve.

The celebration will be the first without iconic host Dick Clark, who passed away earlier this year. He’ll be honored in a tribute show just before the special airs.

Taylor Swift, Flo Rida, Neon Trees, and Pitbull will also perform.
