Tila Tequila tweeted that she was "in shock" over the sudden death of her fiancee, Casey Johnson last night, and now says she's having "haunting visions" of the two of them together.

Early this morning she tweeted, "I can't stop these haunting visions of her and I. We made such a lovely couple, only beginning to spend the rest of our lives together..."

And Tila isn't the only one tweeting her sorrow at the loss of Casey Johnson. Paris Hilton, a good friend of Casey's and her family, posted, "In bed crying, looking at baby pictures of Casey, Nicky and I. I feel so upset. I feel like I've lost a sister. My heart is broken. Miss her." Then, later she tweeted, "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."
