Wash your mouth out with soap, young lady!
We've got to hand it to US pop singer Ke$ha, who has turned cursing into an art form, judging by our latest video above.
TheFIX asked the 'Die Young' singer her favourite swear word of all time and boy does she know how to rip into an F-bomb! Among other unfortunate words involving balls ...
The 25-year-old also volunteered gross-out stories from her time as a waitress in LA before making it big in the music industry three years ago.
One involved finding a cockroach and screwdriver in a customer's food.
"They had to bring it back and I had to try and explain it," she reveals. "But really, I just had to run to the bathroom and throw up!"
"I'm just a really bad waitress. I'm too emotional ... That's why I always tip well it's because I've been there and it f---ing blows!"
Kesha's new album Warrior is out November 30. 'Die Young' is out now.
