Brad Pitt and Angelina Jolie's former bodyguard recently divulged a slew of details about his experience working for them.

Mark Billingham, who goes by Billy, spoke with The Sun recently about being their bodyguard for 18 months and how his responsibilities sometimes extended further than just protecting their safety.

"It's not so much about the physical side, but more about the social side," he noted. "I had to make sure their image was protected, that they were dressed properly and not doing silly things that could be caught on camera."

He noted that Pitt and Jolie weren't exactly the most aware about how to conduct themselves in the general public.

"What surprised me was their low level of common sense. I found it crazy when they would ask me questions like, 'How do I go down to that bar?' and 'What do I need to do to get there?'" he recalled. "They're not stupid, but because of the world they live in they just haven't done something like that for so long. I found that weird."

As for his duties as a bodyguard, Billingham said that Jolie and Pitt were very protective of their children, especially when it came to outside forces.

"Angie and Brad are very worried about who goes near their children. It was clear from the start we had a great chemistry and they trusted me with the kids," he said. "We got very close, I was living with them all the time. I could take the kids anywhere I wanted to on my own. No one else was allowed to do that. Even when I wanted to bring in extra people, they wouldn't let any of those near the kids. They could look out for them from a distance but they couldn't physically touch them. I took them swimming. I fathered them, basically."

Billingham's last quote about how he "fathered" the six kids is certainly raising some eyebrows as Jolie and Pitt continue their struggle for custody. Their children include 15-year-old Maddox, 12-year-old Pax, 11-year-old Zahara, 10-year-old Shiloh and 8-year-old twins Knox and Vivienne.
