TMZ captured Paris Hilton trying to ignite a new trend – scaring the f*ck out of your ex-boyfriend by wearing pictures of him around your neck out in public for undisclosed reasons.

The on-again-off-again coupling of hotel heiress Paris Hilton and shipping heir Stavros Niarchos has our renewed interest. The two have been seen out and about, but Paris’ jewelry leaves us quizzical.

Paris, snapped leaving her house last week, had a necklace on; the open locket has pictures of the estranged couple inside it. One picture shows the couple kissing, the other is a shot of the snuggling twosome.

I mean, I could see if he had been lost at sea or something. But doesn’t she run into him at the club all the time. Brrrrr. This bitch can be so creepy at times. What’s her damage, Heather?
