Singer Ozzy Osbourne flies drones over his neighbours' homes.

The rock band Black Sabbath star and his wife Sharon Osbourne enjoy "spying" on the nearby residents to "see what they're all up to", reports femalefirst.co.uk.

“Ozzy's got a drone and we take it up and spy in on the neighbours' gardens and see what they're all up to,” Sharon said on a radio show.

And while the news may not please some of the people and their families, Sharon, who has daughters Kelly, 30, and Aimee, 32, and son Jack, 29, says she never intends to "hurt people" with the things she does.

“A lot of people really don't like others being opinionated, they would rather you sit on the fence instead of having a strong opinion on something. I get it but that doesn't mean I still don't put my foot in my mouth - I do,” she said.

"I've always been very opinionated. I don't want to hurt people, I don't get a kick out of embarrassing people or being disrespectful, but if you ask me I'll answer. I don't mean to do it in a mean way to anyone,” she added.
