'Jennifer Aniston Is Always Half-Naked!'

Jennifer Aniston is in great shape and knows it, according to a former bodyguard who claims the actress likes to parade around “half-naked” at home.

Apparently one of the perks of being part of the Friends star's entourage is being greeted by a scantily-clad Jen each morning.

"Jen is very free when it comes to showing off her body," the unnamed minder tells Star.

"When she answers the door in the morning, she's wearing a mini camisole and underwear."

The loose-lipped bodyguard claims that Jennifer is known for wearing as little as possible whenever possible.

"She never covers up," the bodyguard continues. "Everyone is used to that. That's just Jen! She's always half-naked."

"When she's not in her underwear she's in a bikini."

The bodyguard adds, "I can name all the moles on her body, that's how many times I've seen her undressed."

We're sure Jen - and current beau John Mayer -  will be reassured to know that her security team are paying such close attention to detail...
