Ozzy Osbourne admits that there's been ups and downs in his marriage, but assures fans that he and Sharon are "back on track."

"We are married, all is good," he shared during an interview on Monday's "Good Morning America" while promoting his new History Channel show, "Ozzy and Jack's World Detour," with son, Jack Osbourne. "'We all lived happily ever after.' I'd like to find the person who wrote that and poke them."

In May, Sharon, 63, and Ozzy announced that they were splitting up after 33 years of marriage following news that the Black Sabbath frontman had an alleged affair. "You just, you make mistakes, and you learn by your mistakes, I think," Ozzy explained on "GMA," adding that their time apart was just "a bump in the road."

The 67-year-old rocker added, "Some days it's good, some days it's terrible, some days you just drift apart for a while. But you get back on the horse, you know."

Ozzy's 30-year-old son has been married for four years and agreed with his father. "As a married person myself, you know, marriage is not like, 'Hey, we're married. All is good,'" Jack confessed. "I mean, it's just life."

In June, Ozzy and Sharon's 32-year-old daughter Kelly confirmed to The Insider that her parents had rekindled their relationship. "My mom and dad are together right now," she revealed. "I will never not be good with my dad. That does not mean that I think what he did wasn't f--king stupid, but that's between him and I. I'm a daddy's girl. I love my dad."
