After recording their last studio album together in 1978, the original members of Black Sabbath announced on Friday that they are reuniting – and RadarOnline.com has the video.

Ozzy Osbourne, Tommy Iommi, Geezer Butler and Bill Ward held a press conference at the Whiskey A-Go-GO in Los Angeles and revealed that they will return to the studio with legendary music producer Rick Rubin this year and also embark on a world tour.  They will also headline Britain's Download Festival next June.
