Stars' numbers appear on the web

Phone numbers of the world's biggest celebrities have appeared on the Internet after computer whizzes hacked into Paris Hilton's mobile.

The FBI is said to have launched an investigation into the scam that has left dozens of stars - including rapper Eminem, actor Vin Diesel, singer Christina Aguilera and tennis star Anna Kournikova - exposed.

After being bombarded round the clock by calls from crazed fans and weirdos, many of the A-list celebrities have been forced to change their numbers. A hacking group, who refer to themselves as 'The Niggas at DFNCTSC', broke into hotel heiress Hilton's T-Mobile Sidekick.

They cracked a pass code to get access to the 24-year-old's phone.

By tapping into the phone they got access to its address book as well as e-mail addresses and private diary notes. It has even been reported the gang managed to retrieve private photos of Hilton from the mobile.

Awebsite posted the numbers over the weekend, accompanied by an offensive message directed at the society starlet. A US government source said the FBI was called in to investigate how her notes, road directions, hotel and airline preferences made their way onto the Web.

Other stars who had their numbers revealed include teen singer Lindsay Lohan, Simple Life star Nicole Richie and tennis star Andy Roddick.

One star told news website The Drudge Report after reporters called the number: 'I gave her my number after we met in Miami, I did not know she f**king kept it on her cellphone.'
