Jennifer Aniston has enlisted the help of some heavies to guard her new $15 million LA property after a photographer almost made his way inside.

The Friends star - who is getting ready to move in to her new pap - has hired three extra bodyguards to scour the property for intruders after a trespassing paparazzo lied about his identity to get inside.

A source tells the National Enquirer, "Jennifer lost it when the construction foreman informed her he had thrown one sneaky photographer off her property.

"He had tried to gain entry by pretending he was an interior designer. Even though she doesn't move in for another two months, Jennifer has hired three security guards to patrol the new estate 24/7."

We wonder why she didn't give on-off boyfriend John Mayer a call to protect her?
