Ozzy Osbourne is adamant his past actions are much more debauched that Justin Bieber's.
The rock legend is well known for his drunk and drug fuelled past, which has included attacking his wife Sharon and biting the head off a bat while on stage.
He insists Bieber's recent bad boy antics pale into insignificance when compared to his own.
"I've got no recollection of snorting those ants, but it beats throwing eggs like Mr F*king Bieber," Ozzy told British Esquire magazine in reference to an event that took place in 1984 when he was on tour with Mötley Crüe.
"We wouldn't have stopped at eggs in my day. I heard he p**sed in a bucket in some restaurant. So what? I p**sed on the Alamo, which is a national shrine. In a woman's dress. At 7am, with a bottle of Courvoisier in one hand, and my dick in the other."
Bieber is being investigated over claims he caused $20,000 of damage to his neighbour's home by pelting it with eggs.
Osbourne found fame as lead singer in heavy metal band Black Sabbath in the '70s. His presence in the showbiz world has never waned, and in 2002 he landed MTV series The Osbournes, a reality show about his family featuring his wife Sharon and their children Kelly and Jack.
But fame and money hasn't brought the happiness that 65-year-old Osbourne expected it to.
"I always thought that having loads of money would mean a happy life. But once you've bought all the things you want, and you're still not content in the world, you have to do a bit of soul searching, and ask, 'Why am I feeling this emptiness inside?'" he revealed.
On the subject of family, Ozzy admits it was a present from his father that has meant the most to him.
"Best gift I ever had wasn't some Bentley or whatever, it was from my father. He borrowed some money and bought me a microphone, and if he hadn't, I wouldn't be here now. I was so ego-ridden and drugged out when he was alive, I never really thanked him for it," he sighed.
"My earliest feeling of emotion was fear. I was always so afraid as a kid. So, when I discovered alcohol, it gave me that Dutch courage I think I needed."
