Staying faithful is deeply important to Sharon Osbourne.
The Talk co-host, who is reportedly divorcing Ozzy Osbourne after nearly 34 years of marriage following allegations the rocker cheated with celebrity hairstylist Michelle Pugh, has long been a vocal opponent of infidelity in marriage. In a throwback interview with ET's Nancy O'Dell from 2011, Sharon candidly addresses how she'd handle unfaithfulness in her own marriage.
"I was really, really disappointed at him for being so horribly disrespectful and deceitful," she said, addressing Arnold Schwarzenegger's past cheating scandal with his housekeeper. "To do that in your own home where your home is meant to be your haven, it's your safe ground, it's your security."
And for what would happen if Ozzy was unfaithful, Sharon didn't mince words: "I'd chop his willy off," she graphically joked. "Arnold's willy would've been down that disposal unit spinning around."
