Ozzy Osbourne has reassured fans that he is in good health after cancelling a recent concert.
The 63-year-old rocker - who is married to 'America's Got Talent' judge Sharon Osbourne and is father to Kelly and Jack - left fans in Germany fearing the worst when he backed out of a gig at the last minute yesterday.
Sources at the SAP Arena in Mannheim, told TMZ.com that Ozzy was supposed to go on stage after the band Black Label Society finished their set.
However the audience were told that he would be unable to perform due to a medical condition.
A representative stated that the rock legend's overall health is OK and he decided to cancel the show due to issues with his voice.
Concertgoers have been instructed to check the venue's official website to see if Ozzy will reschedule or issue a refund.
It was revealed this week that son Jack has been diagnosed with multiple sclerosis.
Last night's German dates were part of a European tour by Ozzy with band 'Ozzy and Friends'. The tour had originally been planned as a Black Sabbath reunion but the cancer diagnosis of Sabbath guitarist Tony Iommi force the group to scale back their plans.
