Socialite and reality TV star, Paris Hilton, recently became the target of hackers as personal information and photos were taken from her T-Mobile Sidekick account and posted online.

Taking credit is a hacker group calling itself DFNCTSC. Among candid and nude photos of the heiress, email addresses and phone numbers of some of the hottest young celebrities were retrieved from her phonebook and posted online.

There were several confirmed phone numbers in the account including such stars as Christina Aguilera, Eminem, Seth Green, Lindsay Lohan, Anna Kournikova, Avril Lavigne, Ashley Olsen, Andy Roddick, Ashlee Simpson, and Usher.

"I got 100 calls in two hours," said Victoria Gotti, daughter of late mafioso John "Dapper Don" Gotti. "I didn't want to take the phones off the hook because my oldest son was out on a date.

"This went on all night," said Gotti, a television actress and writer.

"Finally, at 5:30 am, I took them off the hook. This morning, I put them back on and they started ringing immediately. It's driving me insane," she told the New York daily.

A peek into Paris' daily schedule was taken from her calendar as well; from "Call Maroon 5" to "get birth control kill pill."

The FBI is investigating after a similar incident occurred when a hacker compromised sensitive information from a Secret Service agent's T-Mobile account.

It seems Paris doesn't have much luck these days. A similar incident happened a month earlier when a hacker broke into her BlackBerry account and exposed her private emails. "It became obvious to her what was going on," says a source. "She was pretty upset about it. It's one thing to have people looking at your sex tapes, but having people reading your personal e-mails is a real invasion of privacy."
