The Black Sabbath frontman separated from his wife after 33 years back in May. Tabloid reports claimed that the pair had "mutually agreed" to split, with Osbourne moving out of their family home. It was suggested that the singer had an affair with a celebrity hair stylist.
But in a new interview that aired on ABC's Good Morning America today (July 25), Osbourne said: "Oh, it's [my marriage] is back on track again. You just, you make mistakes, and you learn by your mistakes, I think."
He added: "It's just a bump in the road. 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."
His son Jack also defended the singer adding: "As a married person myself, you know, marriage is not, like, 'Hey, we're married. All is good.' I mean, it's just life.”
Sharon Osbourne wed the Black Sabbath frontman in 1982, having three children together.
Their family life later became the focus of MTV reality show The Osbournes, which aired between 2002 and 2005.
Speaking at the time of the split, she said: "[Ozzy and I] are talking, I spoke to him last night. I'm not with him, but I speak with him."
She added: "He's given me an unbelievable life and he's given me three gorgeous children and I love him. I'm just trying to take it all in, take it all in and process it... I've been avoiding looking at any pictures or reading anything. I know what's gone on, and I don't need to read about it, it's like putting salt in a wound and I don't need to."
