The 67-year-old Black Sabbath frontman updated fans on his status with the 63-year-old television personality on Monday's episode of Good Morning America.
"It's just a bump in the road," Ozzy said of their split. "[The marriage] is back on track again."
"Some days good, some days terrible, some days you just drift apart for a while," he added. "But you get back on the horse, you know."
Sharon had announced her separation from Ozzy in May amid rumors the rocker cheated with stylist Michelle Pugh. The Talk host said at the time that she was carefully considering her future with Ozzy.
"I just need time to think ... about myself and what I really want for the rest of my life," she said. "I love Ozzy dearly. He's given me an unbelievable life. He's given me three gorgeous children and I love him."
Ozzy and Sharon married in 1982 and share three children: daughters Aimee and Kelly and son Jack. The couple were spotted shopping Sunday in Beverly Hills, Calif., after being seen together earlier in the week.
"They're happy hanging out together," a source recently told People. "She's got U.K. X Factor soon and will be traveling over for that."
Ozzy and Jack appeared on Good Morning America to promote their new show, Ozzy and Jack's World Detour. The History channel series, which premiered Sunday, follows the pair as they travel to historically significant spots around the world.
