Demi Lovato is about to embark on yet another world tour—does this girl ever sleep? Before her impending intergalactic takeover, the star stopped by Good Morning America to perform her hits "Neon Lights" and "Heart Attack."
She closed her set with her new single "Really Don't Care" with a surprise duet appearance from Cher Lloyd (basically her British counterpart?)
Whether you're a fan of one or both, it's a great live performance. Watch the clip above!
