Thanks, Paris

In case you're wondering who's to blame for all those phone calls you keep getting...

Half of young Hollywood is reportedly changing their phone numbers today. That's because celebutante PARIS HILTON's private cell-phone records were allegedly hacked into and the numbers of her star pals posted on the Internet over the weekend for the world to see -- and dial.

"If you're one of Paris' pals all of your info is out there for everyone to see," Page Six Reporter PAULA FROELICH says. "We're talking CHRISTINA AGUILERA, LINDSAY LOHAN and EMINEM."

Email addresses were also exposed. Even "The Insider"'s own PAT O'BRIEN, who was listed in the heiress' directory, was spammed. "I'm getting 50 emails a minute!" he told Paris pal BIJOU PHILLIPS at the Daytona 500 over the weekend. "I woke up this morning with 300 missed calls and 400 emails," Bijou exclaimed, "like from people in Ireland and the Netherlands."

Okay, one, someone make sure Pat O'Brien gets his shots. Even if someone found his number in Paris Hilton's address book, why would they e-mail him?

Second, I'm sure all the guys calling Lindsay Lohan will be buying the Barbie doll as well.

Third, when I picture a group of fans at the Daytona 500, I don't usually think of people named Bijou. I guess NASCAR really is getting popular.
