Hilton wore a bejeweled brown frock for the occasion, along with Hollywood's hottest new noggin accessory, a headband. Of course, Paris being Paris, her variation on the theme was more bling-laden than most.

Not that Hilton was completely untraumatized by the domestic break-in. Hilton tells Life & Style magazine, "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. I'm just thankful that I wasn't there when it happened."

According to an insider, Hilton lost millions of dollars in jewelry—"diamonds, necklaces, rings, watches and family heirlooms from her grandmothers"—in the heist.

The thief was wearing a black hoody and knew exactly where to go, like he's been there before."

Since the robbery, Hilton has focused on safety, the source says: "Paris has upped her security team to three 24-hour bodyguards, and she has someone on her property at all times."
