Paris Hilton has been left devastated by the news of fellow socialite Casey Johnson's death.
The Johnson & Johnson heiress, 30, was found dead in her Los Angeles home on Monday morning (04Jan10) and Hilton has been among the first people to comment on the tragedy.
She tells Life & Style magazine, "I am devastated to hear this news. I've known Casey since I was a baby.
"She had a big heart and she was a good friend. I feel so sad, I don't want to believe it. My condolences go out to her family and loved ones."
The Hilton sisters were so close to Johnson, Paris' sibling Nicky was godmother to the socialite's adopted daughter, Ava, three.
Los Angeles police have confirmed that they believe the death was "natural" and that no foul play was suspected. Toxicology reports are still to be conducted.
