PORN star Olivia Lua has died aged 23 - the fifth adult actress to pass away in just three months.
Olivia, who was sometimes known as Olivia Voltaire, died in rehab, her agency confirmed on Friday night.
A statement blamed a mix of prescription drugs, recreational substances and alcohol.
She is now the fifth XXX star to die with Yuri Luv, 31, August Ames, 23, and Shyla Stylzez, 35, all passing away recently.
Olivia Nova, 20, was also found dead in her apartment after a UTI infection turned into deadly sepsis.
In December, Ames killed herself after she was trolled on social media for refusing to film a sex scene.
Lua's agency LA Direct Models said in a statement: "Much comment has recently been made on the number of adult stars having passed in the last year and with great sadness we must inform that the list has grown longer.
"We learned today that Olivia Lua passed away this morning - may she rest in peace."
A spokesman revealed Olivia had been battling drug addiction, and had recently suffered a catastrophic relapse.
The statement added: "We learned today that she had returned to a different facility in West Hollywood after a relapse, approximately a week ago, at which she was found deceased this morning."
She posted a cryptic final Tweet just three days ago which read: "I feel it everywhere, nothing scares me anymore."
The Tweet was accompanied by a picture of her dressed all in black.
The sudden spate in actress deaths has raised question marks over the safety net offered to performers.
