Simon Cowell has never been afraid to speak his mind, and he and Gordon Ramsey are tied for the most aggressively critical TV hosts on the air today. Needless to say, Cowell has probably made himself a list of enemies, and he’s right to keep a bodyguard close by (though sometimes he’s a softy).

The American Idol judge hired “Big Tony” Adkins as his bodyguard for years. Adkins worked for him when he was a judge on Britain’s Got Talent and The X Factor, spanning an eight-year period. Adkins would later go on to become an actor, portraying a giant in Harry Potter & the Deathly Hallows.
