Slipknot’s Sid Wilson popped the question to Kelly Osbourne... right in front of her dad, Ozzy.

During Black Sabbath’s historic final concert, Slipknot’s Sid Wilson popped the question to Kelly Osbourne... right in front of her dad, Ozzy.

The Prince of Darkness gave the most Ozzy response ever: “F*** off! You’re not marrying my daughter!” (Don’t worry, he was joking.)

Just another legendary moment from a night full of metal history.
