Guy Ritchie’s pending divorce from Madonna has made him a target for the pop legend’s obsessed fans.

Police were called to Guy’s London pub, The Punchbowl, last Thursday night after a a 16-year-old boy wielding a knife burst onto the set of his Sherlock Holmes movie remake and threatened to kill the director.

According to Britain’s Sunday Mirror, the unidentified teen could be heard shouting, “I’m Madonna’s biggest fan! I’m gonna kill Guy!”

“The bloke was screaming about Guy and shouting, ‘I love Madonna’. It was terrifying. At first it seemed like a sick joke but it was soon obvious the knifeman was not messing around.”

The insider adds, “Luckily there were four security guards and two policemen who were able to overpower him.”

“Guy was understandably upset, but carried on as if nothing had happened.”
