Kelly Osbourne and Sid Wilson got engaged at Ozzy Osbourne's final concert — right after the Prince of Darkness weighed in on the Slipknot DJ marrying his daughter.

Kelly Osbourne, daughter of rock legend Ozzy Osbourne, is now engaged to Slipknot turntablist and keyboard player Sid Wilson. The TV personality shared a video to her Instagram on Sunday of Wilson popping the question backstage at her father's final show with his pioneering heavy metal band, Black Sabbath.

Sharon told TMZ that while Wilson asked Ozzy for permission to marry their daughter months ago, the rocker did not know the timeline—and for sure didn’t expect the big moment to take place on the night of Sabbath’s farewell show. She said her husband was shocked by the proposal.
