Casey Johnson dead at 30

Casey Johnson, the heiress to the Johnson & Johnson fortune who recently made tabloid headlines with a purported engagement to reality star Tila Tequila, has died at age 30.

Los Angeles police and firefighters were called to a house at 11:51 a.m. Monday. Johnson was pronounced dead at the scene. A law enforcement says it appears Johnson had been dead for several days before her body was discovered.

Casey was the great-great granddaughter of the founder of the pharmaceutical giant, and the daughter of New York Jets owner Robert Wood Johnson. She was mother to a three year-old girl, Ava. Johnson adopted Ava in Kazakhstan in 2007, but the little girl is now in the custody of Johnson’s mother, Sale Johnson, in Manhattan.

Tila Tequila (real name: Tila Nguyen), 28, also confirmed the tragic news on her Twitter:

“Everyone please pray 4 my Wifey Casey Johnson. She has passed away. Thank u for all ur love and support but I will be offline to be w family”

An openly gay socialite, Johnson had a knack for attracting paparazzi – and trouble. A nasty fight with ex-girlfriend Courtenay Semel, daughter of former Yahoo chief Terry Semel, reportedly resulted in Johnson’s hair catching on fire last October. Then in November, she was arrested for allegedly breaking into another former girlfriend’s house.

In December, Tequila announced the pair were engaged. “Tonight, my beautiful girlfriend has just asked me to marry her and check out this rock,” the lingerie-wearing Tequila said in an Internet video. “Bam! That is a 17-carat diamond ring from my baby.”

Casey Johnson had a history with drug abuse. Johnson recently left a stint in rehab – early.
