The original Black Sabbath line-up of Ozzy Osbourne, Tony Iommi, Geezer Butler and Bill Ward are reuniting for a new tour and album.
The Birmingham Mail revealed the news in August as the closest guarded secret in rock music was made public.
But the news became official as the band made an announcement on their website at 11:11 am (Pacific Daylight Time) on November 11.
The band also directed fans and the media to the Whisky A Go Go nightclub in Los Angeles as speculation reached fever pitch on social networking sites.
The band are recording a new album with Rick Rubin and will tour the world in 2012.
They will headline the Download Festival at Donnington Park in June.
