Porn star Olivia Nova, who rose to fame in the adult film industry in just a matter of months, has died at the young age of 20.
The Minnesota native was found dead in Las Vegas on January 7.
The cause of death is still not known, her agency, LA Direct Models, said in a statement released Monday.
On Christmas, Nova posted on Twitter that she was spending the holidays alone. The post said she wanted to 'give a fan a call' to 'lift my spirits'.
Nova's death comes less than a year after her boyfriend committed suicide. In a tweet earlier in December, she said he killed himself two days before her birthday in April.

Nova started acting in pornographic films in March of 2017.
'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,' LA Direct Models said, according to XBIZ.com.
'It is understood next of kin have been informed,' they added. 'Another one, way too young we are beyond shocked and most certainly, completely out of the blue. Rest in peace, sweet angel.'
Derek Hay, owner of LA Direct Models which signed Nova just before Christmas, described her as a 'sweet, mild-mannered girl'.
'It's very very sudden, she was really a sweet, mild mannered girl, we're very saddened by her death, she was only 20,' he told DailyMail.com.
'We had no inclination of any problems with her at all. I've spoken to a couple of friends of Olivia's and I have spoken to the coroner's office and her death is a mystery. Suicide isn't suspected and it doesn't seem anyone else was involved.
'Somebody must have been with her in the hours that preceded her death and if that person emerges we may learn more, but the death is not considered suspicious. There will be a post mortem but we won't get the results for six to eight weeks.'

Hay said Olivia - whose real first name is Alexis - had only been signed up to LA Direct Models for two months and she had been in the porn industry for just a year.
'We sent her to shoot in Prague and Paris which she completed, returning from that trip just a few days prior to Christmas. I have been speaking to Olivia regularly, she lives in Vegas, my office is in Vegas. She wanted to move from one agency to my own and we met several times to discuss the possibility of doing that.'
Hay says Nova died at a private residence in Vegas but not her own place and there was indication she was depressed despite tweeting she was spending the holidays alone.
He said the death - the fourth in porn in recent months - has rocked the industry.
'We're keenly aware, this is the fourth death in the porn industry in the past three months, it's incredible,' he said.
In an August interview with photographer Dave Naz, Nova said that she was shaking with nerves the first time she stripped for a project. But she said she was comfortable 'within seconds'.
She also said she had aspirations outside of the industry.
When asked where she saw herself in 10 years time, she said she planned on graduating school.
'I also have this huge project, it's non profit, that I want to be a part of,' Nova added.
Nova is the fourth porn star to die in recent months. August Ames, 23, committed suicide on December 6 while Turi Luv died in August from a drug overdose.
Shyla Stylez, 35, died in November and her cause of death is still unknown.
