Mourning Tequila
The 28-year-old bisexual reality TV star, Tila Tequila (real name: Tila Nguyen) also announced the tragic news on her Twitter page.

"Everyone please pray 4 my Wifey Casey Johnson," Tequila wrote. "She has passed away. Thank u for all ur love and support but I will be offline to be with family."'

About the heiress’ past
Casey was the mother of three year-old girl, Ava, whom she adopted in Kazakhstan in 2007. The toddler girl is now in the custody of Johnson's mother, Sale Johnson, in Manhattan.

Casey became a media fodder for various disgraceful reasons, including her nasty fight with ex-girlfriend Courtenay Semel, daughter of former Yahoo chief Terry Semel. The fight, which took place last October, resulted in Casey’s hair catching fire.

Casey, who had a history of drug problems and failed at rehabilitation several times, was arrested Nov. 30 for allegedly breaking into another former girlfriend's house.

She was also arrested on felony charges of theft and receiving stolen property, accused of taking $22,000 worth of jewelry, underwear and other items from Jasmine Lennard, a model and British reality TV star.

In December, Tequila, the star of "A Shot at Love With Tila Tequila," which ran for two seasons on MTV, 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 online video. "Bam! That is a 17-carat diamond ring from my baby. My baby is a billionaire!"
