While Hollywood gossips about who was - and wasn’t - in Paris Hilton’s cell phone book, the hotel heiress/reality TV star says she feels “horrible”.

Last week, Hilton’s cell phone was hacked into and its contents (her phone numbers and email addresses) were posted on the internet.

In an interview with Us Weekly magazine, on newsstands Friday, Hilton says: “I feel horrible that, once again, someone has invaded my privacy. I want to apologise to all my friends and family. I don’t know why this stuff always happens to me, but I wish it wouldn’t anymore.”

Hilton, 24, said she first heard the news from her sister, Nicky.

“Nicky told me it was out there,” she said. “It’s too upsetting for me - I can’t believe it.”

Some of her friends have been besieged with calls and emails.

Actress Lindsay Lohan tells the magazine: “It’s crazy. I even got an email from someone pretending to be Hugh Hefner.”

Hilton’s privacy was previously exposed when a sex tape of her and an ex-boyfriend became a cyberspace novelty. She stars on the Fox TV reality show The Simple Life 3: Interns with friend Nicole Richie, daughter of R&B singer Lionel Richie.
