Footage surfaces of Jackson's hair burning

US Weekly magazine has obtained video it says shows never-before-seen footage of Michael Jackson's head catching on fire during filming of his 1984 Pepsi commercial.

Jackson suffered severe burns after a pyrotechnics mishap. Still photos of the accident have appeared, but the new video on Us Weekly's website shows the moment Jackson's hair caught on fire and the top of his head became engulfed in flames.

Jackson doesn't appear to know his hair is on fire. In the video, he's still dancing as the flames are on his head. When he spins, the flames go out. People on the set tackle him to extinguish the fire. When Jackson emerges, the top of his head is bald.
