Rocker Ozzy Osbourne and his wife Sharon were forced to flee their home on Friday night after a blaze broke out while they were asleep in their mansion.

The former Black Sabbath star and 'X Factor' judge Sharon were in bed when the fire started in their living room late at night.

After the fire alarm went off they ran into the garden, along with their pets, as firefighters rushed to their home in Buckinghamshire.

Two fire engines turned up and four firefighters brought the blaze under control. It is thought to have caused thousands of pounds' worth of damage.

Fire investigators are examining the cause, which may have been electric.
