Ozzy Osbourne's secret for staying married to Sharon Osbourne for 26 years: "Get a good crash helmet on my head," the heavy metal musician, 59, told PEOPLE on the red carpet at the Marshall Classic Rock Roll of Honor Awards in London Monday night.
"When she gets pissed off, I really go up in the air."
And while some reports are suggesting that daughter Kelly Osbourne, 24, and boyfriend Luke Worrell are headed for an engagement, Kelly's father is careful not to offer her any relationship advice, he told PEOPLE.
"She'll end up going, 'Dad shut up!' "
Osbourne was at the event to accept the Living Legend Award for his career as lead vocalist of Black Sabbath.
