Sharon Osbourne plans to make her husband Ozzy pay for his infidelity for the rest of his life.

The couple has patched up its marriage after the rock star's cheating scandal led to a brief split earlier this year (16), and now Sharon insists things are good again.

But she won't let her husband forget what he did to her after she learned about his affair with hairdresser Michelle Pugh.

During an appearance on U.S. chat show Conan on Tuesday (27Sep16), after Sharon was asked if she was going to make Ozzy pay for his actions, she chuckled, "Oh, big time. Yes!"

But, confirming all is well in the marriage again, Sharon revealed she has always had problems with her husband's addictive nature, adding, "It’s tough, you know, when you’re an addict. He likes too much alcohol, he likes too much drugs, he likes too much sex. Everything is too much, so it's tough for somebody that suffers with that."

Sharon also told Conan host Conan O'Brien she wasn't impressed with her husband's mistress, insisting she thought he'd pick someone better looking: "I said, 'My God, you do need glasses! Who would do that with that?'"

Ozzy underwent therapy for sex addiction after news of his extramarital affair broke and he publicly apologised to his family for the shame his behaviour caused.

"Over the last six years, I have been dealing with a sex addiction,” he said, according to Us Weekly. “I am mortified at what my behaviour has done to my family. I thank God that my incredible wife is at my side to support me.”
