Paris Hilton, the globetrotting hotel heiress whose sex tape with an ex-boyfriend flew around cyberspace, has been exposed online in a different way.
Authorities believe somebody hacked into her personal cell phone, stole the phone numbers of her friends, then posted them on the internet.
And since then, the phones of some of her biggest celebrity friends have been ringing off the hook.
Those big-name stars include Eminem, Christina Aguilera, her own sister.
Nicky, and even tennis star Andy Roddick.
Not only that -- racy photos and personal text messages also made their way onto the Web.
Ironically, the device -- a "T-Mobile sidekick," is the same product she's been endorsing in commercials.
Investigators suspect the hacker involved bypassed T-Mobile's online security system.
The company says its investigating, but ordinary cell phone users are concerned.
"I just think it's completely unfortunate that we can't leave our cell phones on anymore," says student John Lind.
"The lack of security -- you shouldn't even have to worry about it."
The security breach will likely force many to think twice before giving out their cell phone numbers.
