Sharon reveals Ozzy tried to put out blaze while wearing sling

Ozzy Osbourne's hair caught fire because of an unattended candle.

The rock legend suffered a painful burn that left him with a "very weird haircut" in December 2012 after his wife Sharon Osbourne left a candle - which was a Christmas gift from former 'America's Got Talent' judge Howard Stern - burning overnight at their Los Angeles home, causing their living room to burst into flames.
