Demi Lovato may really not care about her haters, but she loves her Lovatics! The singer proved how connected she is with her fanbase during a show-stopping performance in Central Park for 'Good Morning America.'

She was every inch the confident, self-assured star in black pants and a black top with a fresh white blazer. She added a pair of amazing graphic heels to complete the outfit. Of course, the look also showed off Demi's newly dyed purple and silver locks.

Demi kicked off the set with her latest single, 'Really Don't Care.' She pumped up the crowd, leading them in a series of fist-pumps to punctuate the upbeat chorus. One thing the audience wasn't expecting? An appearance from the song's featured artist, Cher Lloyd! The pint-sized singer joined Demi onstage, much to the fans' delight.

Demi closed out her set by performing three of her other hits, 'Neon Lights,' 'Heart Attack' and 'Give Your Heart a Break.' Check out her duet with Cher Lloyd in the video above and the other songs in the videos below!
