In more recent years, Kesha has managed to show the world a more serious and grounded side of herself. And she’s also lent her talents to other musicians—like Britney Spears.
The “Tik Tok” singer helped pen Spears’ 2011 comeback hit, “Till The World Ends.” In an interview with MTV shortly after the song came out, Kesha divulged that she wrote this song with the specific intention of helping Spears find her footing in the music industry once again. “That song is me imagining her and any female musician touring the world,” she said. “You know, when you go out, and you’re having an amazing, magical night and you don’t want to go to sleep and you want it to last until the world ends.”
