Johnson & Johnson heiress Casey Johnson died last Monday at the age of 30. Johnson was found dead in her Los Angeles home and although it appears to be a natural death, a toxicology report is being done. The heiress was engaged to reality TV star Tila Tequila, who tweeted about the news: “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.”

Johnson, who was openly gay, was the daughter of New York Jets owner Robert “Woody” Johnson and great-great-grand-daughter of Robert Wood Johnson, who co-founded the Johnson & Johnson health care empire.

In 2007, she adopted a daughter, named Ava from Kazakhstan. Johnson had a history of drug problems and has failed at rehab several times, according to several news sites.

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 in the following video:
