Home invasion leaves Paris more than shaken.

Hilton’s terrified the thief who broke into her mansion may be somebody she knows because the burglar knew exactly where the hare brained heiress kept her most precious belongings.

According to cops, the intruder is believed to have entered through the front door of Hilton’s Sherman Oaks abode before ransacking Paris’ bedroom, making off with an estimated $2 million in jewels.

“I think whoever did this definitely has been there before,” the socialite detective revealed after viewing surveillance tapes.  “We have some suspects that I’m thinking of.”

She’s convinced authorities will have the possible frenemy behind bars soon.

“It’s really scary but they’re doing a huge investigation on this and we’re going to catch this person.”
