THERE’S no one who understands the dangers of fame better than a Hollywood star – or, perhaps more accurately, their security chief.

Over the years, celebrity bodyguard Simon Newton has protected some of the most famous people in the world – including Michael JacksonKendall Jenner and Bella Hadid – and says there’s one threat they all face.

Speaking to The Sun, Simon – who now owns his own private security business and works as an actor – says stars are constantly bombarded by messages from stalkers, who pursue them online, at the shops and even at red carpet dos.

“Fans don’t get aggressive,” Simon, 43, says. “The most you get is diehard fans, pushing and shoving, and getting a little bit over-excited to see the person.”

“But, with stalkers, there can be a real, physical threat there at times, and that’s quite a big thing we’ve seen over time, but it’s all connected to mental health.”

He continues: “Most celebrities have some sort of a stalker, at some point in their lives, and it might not just be someone sitting outside their house.”
