At today's American Music Awards, Kesha took to the stage with Big Freedia to perform a live rendition of their new song 'Raising Hell' from Kesha’s upcoming album High Road.
But the 32-year-old star had a surprise up her sleeve - and it arrived in the shape of her original smash hit, 'TiK ToK'.
Breaking into the 2010 track had the audience jumping to their feet, with one man's on-camera jaw-drop reaction quickly going viral.
The performance was especially powerful given it was originally produced by Dr Luke, with many fans observing that Kesha's live rendition felt like a taking back of power.
When the United States rang in the new year back in 2010, 'TiK ToK' was sitting pretty at number 1 on the Billboard music charts - and stayed there for another 9 weeks.
Over the following 10 years, Kesha experienced a roller-coaster pop music career; releasing three full-length studio albums and, in 2014, going public with allegations of abuse against music producer and former mentor Dr Luke, and attempting to extricate herself from her recording contract with Sony Music.
However, the star now seems to be enjoying a moment of celebration and reflection.
"Kesha reminding us that TiK ToK is the greatest song ever recorded," one Twitter user wrote.
Another tweeted: "kesha just showed gen z kids what tik tok really means," referring to popular short-video social media platform Tik Tok.
According to Rolling Stone, Kesha’s upcoming album, High Road, features collaborations with Sturgill Simpson, Brian Wilson, Dan Reynolds of Imagine Dragons, Nate Ruess of Fun. and is due for release early January 2020.
Will she ring in the new decade at number 1 once more?
