Protecting Whitney

David Roberts was Whitney Houston's bodyguard, the real one.

Roberts was hired in 1988 for Houston's UK portion of the Moment of Truth world tour. Accustomed to working for diplomats and Fortune 500 clients, Roberts had reservations about working with a pop star. But Houston's heart of gold won him over from the moment they met at Heathrow airport.

There's a high bar for those who work in this business: you must be willing to die for your boss. Houston made that easy. Roberts got to travel the globe with one of the most fun-loving and generous souls he'd ever met. His memoir reveals heartwarming anecdotes of life with one of the world's most recognizable stars, including privately shared moments such as the birth of Bobbi Kristina.

But there are also shocking and heartbreaking revelations. Roberts was present for some of Houston's most challenging ordeals. And he was helpless as he watched those who claimed to love and support her betray her confidence for their greed.

His heart was ultimately shattered as he witnessed her succumb to the one threat he could not protect her from: herself.
