The first lady of heavy metal, Sharon Osbourne, dumped a bucket of water on a London cameraman who sprayed her with a squirt gun that looked like a microphone.
"I think it was supposed to be a joke, but Sharon was taken aback and saw red," witness Simon Lloyd told the newspaper.
Osbourne "was terrified it might have been acid or ammonia," a source told the newspaper.
Osbourne declined comment on the incident.
