When Jackson stepped off the private jet in Las Vegas, his entourage consisted only of his children and their nanny.
"He was all alone," Whitfield recalled in a CNN interview. "It became an unreal thing. Something's not right. This is a joke."
The guards, who sometimes went for months without pay, often used their own money to fund the household when Jackson's credit cards were declined.
Lawsuits and debt collectors hounded Jackson. The guards often drove the singer to lawyers' offices for depositions where he would have to answer questions for hours.
His managers were "beefing with security" and "doing deals behind his back," Beard told CNN. "The guy was mentally exhausted."
Whitfield and Beard revealed that Jackson did have a secret distraction, known only perhaps to some of his more obsessive fans. Jackson had girlfriends. The guards' book details short visits Jackson would make to hotels to visit with two women known to them only as "Friend" and "Flower."
The King of Pop would have make-out sessions with a woman behind a curtain in the backseat of his SUV as his guards drove, they said.
"When we actually saw that he really does like girls, we were high-fiving," Beard said. "We knew it! To be able to see him kissing it was 'Yes!' Seeing it for our own eyes."
The women, who the guards believed to be from Europe, never visited his home and never met Jackson's children. He would always return home from his dates before Prince, Paris and Blanket would wake up in the morning, they wrote. They remained a secret part of his last years.
Jackson instructed his guards to keep his brothers, sisters and father away, although his mother was always allowed to pass through his gates, they said. Jackson's relationship with most of his family seemed "null and void" in those last two years, Beard said.
