Flames scorched Ozzy and Sharon Osbourne's English country mansion Thursday morning, the result of a faulty lamp, the fire service said.

Neither the couple nor their children, Amy, Jack and Kelly, were at the house in Jordans, 26 miles west of London, when the fire occurred, a family spokesman said. Paramedics treated a member of the household staff for smoke inhalation.

Kelly Osbourne, 22, had left shortly before the fire broke out.

The Buckinghamshire Fire and Rescue Service responded after the family's alarm system alerted them, spokesman Fraser Pearson said.

"We were able to prevent the fire from spreading," Pearson said. "It was relatively small."

The blaze caused minor fire and smoke damage to the entrance hallway of the mansion.

Pearson said the fire service plans to try to meet with the Osbournes to advise them on fire safety, Pearson said.

Ozzy and Sharon Osbourne had to flee the mansion last year when a fire broke out in their living room. In 2004, Ozzy Osbourne, who earned fame as a heavy metal rocker in the 1970s, unsuccessfully tackled a thief as he raided the house and stole a large amount of jewelry.

And in December 2003, Ozzy Osbourne broke his collarbone, several ribs and a neck vertebra in an all-terrain vehicle accident on the grounds of the estate.
