Porn star Olivia Nova has died at age 20, her agent confirmed Tuesday.

LA Direct Models said they were “beyond shocked by the sudden death,” the cause of which is currently unknown.

Nova was found dead in a home in Las Vegas just a few days after she tweeted about being alone on Christmas.

She said: “Alone on the holidays and want to give a fan a holiday call.”

“Would lift my spirit.”

LA Direct Models’ statement said: “While only represented by Direct Models for a short period of time, we came to know Olivia as a beautiful girl with a very sweet and gentle personality.”

“Another one, way too young, we are beyond shocked and most certainly, it was completely out of the blue.”

“Rest in peace, sweet angel.”

The tragedy comes after a spate of deaths among porn stars in the US.

Nova has become the fifth to die in the adult film industry in the last three months.

Yuri Luv, 31, August Ames, 23, and Shyla Stylez, 35, all passed away recently.

In December, Ames committed suicide after she was trolled on social media after refusing to film a sex scene with a man who had also shot gay porn.

Fellow porn actresses, including Jenna Jameson, blamed her death on online criticism.

A week after Ames’ death, Luv died following an alleged drug overdose.

Stylez passed away in November.

Nova began her career as a model after she was scouted at the age of 12.

But she only moved into the adult film industry in March 2017.
