"Don't stop, make it rock!" Kesha must still take that advice from her single "Tik Tok" a decade later. The 32-year-old singer stepped onto the American Music Awards stage on Sunday night for the first time in six years. She started things off with a passionate rendition of her new song, "Raising Hell" featuring Big Freedia, followed by a revival of her 2009 breakout hit, which earned quite a reaction from the crowd.

The audience in real life and online could not contain their excitement, resulting in an enthusiastic response and plenty of funny tweets. Ahead, see a few of our favourite reactions to Kesha's surprise performance. We love a good throwback, and clearly her fans do too!
