Tila Tequila says she is struggling to cope with the sudden death of her purported fiancee, Casey Johnson, the heiress to the Johnson & Johnson fortune.
"I can't stop these haunting visions of her and I," she wrote on her Twitter early Tuesday morning. "We made such a lovely couple, only beginning to spend the rest of our lives together..."
Johnson's childhood pals, Paris and Nicky Hilton, also are struggling. (Paris originally asked Johnson to costar with her on the Fox reality show, The Simple Life, but Johnson turned the offer down; Nicky also is godmother to Casey's adopted daughter, Ava, 3.)
"In bed crying, looking at baby pictures of Casey, Nicky and I," Paris Twittered. "I feel so upset. I feel like I've lost a sister. My heart is broken. Miss her."
A short time later, Paris added, "God has another Angel by his side. Casey, we all Love and Miss you and know that you are in a better place. R.I.P"
The 30-year-old Johnson -- known for her wild partying ways that included drugs and alcohol -- was found dead around 11:51 a.m. Monday in her Los Angeles home.
Her death may have been from natural causes since a preliminary investigation turned up no signs of foul play. A final cause of death will be determined by coroner's officials, who will seek toxicology tests. Results of those tests could take six weeks to obtain.
In a statement to UsMagazine.com, her family says it "is mourning its tragic loss, and asks for privacy during this very difficult time."
