Update: Paris Hilton's Phonebook, Nude Pics Leaked to Web

(andPOP) - What is believed to be Paris Hilton's phonebook was leaked to internet web sites over the weekend.

Over a hundred email addresses and phone numbers, believed to be listed in Hilton's T-Mobile Sidekick address book, are listed. Among them are her father, her sister, Ashlee Simpson, Christina Aguilera, Fred Durst, Eminem, Anna Kournikova, Lindsay Lohan, Fergie of the Black Eyed Peas, Jay-Z, Pharrell Williams of the Neptunes, and Lil Jon.

Also being sent around the web are her private notes and directions.

In January, a hacker was able to read her emails sent to her Blackberry. The hacker was never caught, and it is unknown if there is a link between the two incidents.

The FBI is investigating, according to the Drudge Report, which first reported the information Sunday morning.

A story in January revealed a hacker was able to crack into T-Mobile's system and uncover information from numerous accounts. It is unknown if there is any relation to this incident as well.

This story is still developing.

Update: Sunday 1:55 PM ET
Photographs from her phone were also leaked. They show Paris Hilton with friends such as Nicole Richie.

Some photos show Hilton nude, kissing an unknown female friend.

The pictures were posted by the hacker, but have been pulled from the server they were originally posted on.
