Speculation surrounding a Black Sabbath reunion including Ozzy Osbourne arose in August, when the Birmingham Mail reported that Sabbath guitarist Tony Iommi said the original lineup was writing new material together. Iommi back-tracked on his official website, expressing disappointment that his statements -- reportedly told in confidence -- made waves. But he never actually denied the claims that the heavy metal gods were collaborating in some capacity.

Speaking with Billboard.com regarding his upcoming second book, "Trust Me, I'm Dr. Ozzy," Osbourne also touched on the swirling Sabbath reunion rumors. "Yes, it's a very, very strong possibility," he says of getting the old band back together. "It's in the very early stages, so we haven't recorded anything yet. If it works out, it'll work out. If it doesn't, I'll keep doing my thing."

Osbourne's founding group may be taking it slow, but it doesn't mean the "Bark At the Moon" singer is. His "Dr. Ozzy" book, based on his health and sex advice columns of the same name in Rolling Stone and the UK's Sunday Magazine, hits stores Tuesday (Oct. 11), with a book tour to follow. "I'm not trying to be the next f**king Dr. Phil," he says of his Dr. Ozzy persona, which he views as mostly common sense from a formerly hard-living rocker who's been pronounced dead -- twice.

Osbourne's outspoken wife Sharon has been keeping quite busy as well, specifically with TV endeavors including her "America's Got Talent" judging spot and a return to CBS talk show "The Talk" yesterday (Oct. 6) following a brief health-related absence. The Osbourne clan knows its way around TV cameras, but would Ozzy ever return to the reality show world that escalated his family to celebrity status? "Sharon loves TV and I don't have any problem with that, but I just don't like doing it," he says. "It's alright doing an ad or a quick spot for the camera, but I just don't like doing the TV shows."

'This Was About More Who He Is As a Person'

Osbourne remains supportive of his multi-facted other half, and colors himself something of a feminist. "I think the person who said women are the weaker sex is a f**king idiot," he says. "I cannot accept the fact that women are the weaker sex. I remember my wife giving birth to one of our kids, and then she was right back on the phone fighting [Sharon is Ozzy's longtime manager]. I'm like, 'Are you kidding?'"
