Johnson Family Wants Larry King to Cancel Tila

Tila Tequila is scheduled to appear for the full hour tonight on Larry King Live, but family members and friends of the late Casey Johnson are reportedly urging King to cancel.

Tequila, who announced in an Internet interview that she and Johnson were engaged just one month before the heiress's death, continues to insist the relationship was real despite numerous reports it was all a publicity stunt.

"The Johnsons just want Tila to go away," a source told E! Online. "They're in mourning. She is the last thing they want to deal with right now.

"Everyone knows the tabloids won't back away from Tila, but they didn't think Larry King would actually consider having her on his show," the source said. "They've called him and sent him emails asking him to cancel the interview."
