A BURGLAR broke into PARIS HILTON’s new home and stole £1.3million of jewellery from her bedroom, SUN reports

Paris, 27, was out with singer pal CHRISTINA AGUILERA, when the thief forced open the front door of the £4million Hollywood mansion.

LAPD spokesman Ben Llewellyn said: “A security guard

is the one that called in and reported that the residence was broken into.

“Our detectives learned that a man wearing a hooded sweatshirt and gloves forced entry through the front door.

“The man ransacked the bedroom.”

Having viewed her home surveillance tapes, Paris Hilton doesn’t think a stranger is responsible for burglarizing her Sherman Oaks, Calif., abode.

“I think whoever did this, definitely has been there before,” the ripped-off heiress told E! News Monday while perusing the racks at the L.A. boutique Intuition. “We have some suspects that I’m thinking of.”

Nearly $2 million worth of jewelry and personal items were stolen from Hilton’s recently purchased mansion early Friday morning, while the newly single socialite hung out at Hollywood hotspot Bar Deluxe.

Police said that a man in a hooded sweatshirt and gloves forced his way through the front door and ultimately focused on Hilton’s bedroom for his ill-gotten gains.

The items taken included “jewelry, watches, every ring I own,” Hilton said. “All my necklaces, jewelry that my grandmothers gave me that I’ll never be able to replace.

“You know, it’s just an invasion of privacy and it’s happened to me before. It’s really scary but they’re doing a huge investigation on this and we’re going to catch this person.”

The reality-TV star said that, initially, she was afraid to be in the house after the break-in, but she has since “upped the security majorly.”

“Obviously it’s devastating and disturbing that someone was in my home,” Hilton said. But “we have three security guards there and a 24-hour guard who is always on my property,” Hilton said. “We have the alarm on, the dogs we have, the guards with the gun, so, no one is going to be coming into my house.”

Hilton also has a message for the person or persons responsible for shattering her sense of security:

“I would tell them to please return my things, because I know that they’re probably watching E! News right now, to return everything and that’s it,” she told us.

“They just have to anonymously have a taxi drop it off in my front gate in a box with my jewelry and everything they won’t get in trouble, but if all this goes on for much longer they’re going to get in more trouble.”
