Ozzy and Sharon Osbourne (search) had to flee their English mansion when a fire broke out in the living room, a British newspaper reported Thursday.

The Sun tabloid said the couple were alerted by a fire alarm and ran into their backyard when the blaze broke out late Friday at their house in Buckinghamshire county, northwest of London.

A spokeswoman for Buckinghamshire Fire Service (search) confirmed that two fire engines had been sent to a blaze at a house in the area. Two men and a woman were treated for minor smoke inhalation, she said.

Fire officials were investigating the cause of the blaze, suspected to be an electrical fault.

The fire was the latest in a series of domestic mishaps to befall the former Black Sabbath (search) frontman and his manager wife, a judge on the TV talent show "X Factor." Last year Ozzy hurt his shoulder in a quad-bike accident on the grounds of his English home, and tackled a burglar who stole gems worth an estimated 2 million pounds (US$3.6 million) from the mansion.
