Paris Hilton ParisHiltonRobbed.jpgThe theft of nearly $2 million dollars worth of jewelry and other personal items from Paris Hilton's Hollywood Hills home has left the heiress "devastated," Life & Style reports.

"I am devastated. I cannot believe someone broke into my home. They took items that had such sentimental value that no one will ever be able to replace," Hilton tells the mag. "I'm just thankful that I wasn't there when it happened."

Paris has also reportedly increased her security since the break-in.

"Paris has upped her security team to three 24-hour bodyguards, and she has someone on her property at all times," a source close to Paris tells Life & Style.

Paris wasn't home when thieves entered her home last Thursday, reportedly making off with diamonds, necklaces, rings, watches and family heirlooms.
