Demi Lovato headlined our Kiss Concert '13 and not only did we all get to hear a bunch of songs off her NEW album BUT we got to watch her perform, 'Really Don't Care' for the first time ever...and Cher Lloyd joined her on stage!

Demi leaked the album herself a week before it was released. After being on iTunes for 9 hours, 'Really Don't Care' featuring Cher Lloyd, became the biggest seller off her self titled album 'Demi.'

Fellow Kiss Concert performer Cher Lloyd is featured on the track and the two teamed up for a one of a kind performance of the sassy song.
