Horror queen Elvira's tell-all book claims she was sexually assaulted by NBA great Wilt Chamberlain: 'When a 7-foot-1, 300lb man has his hand wrapped around your neck, there's really not a lot you can do'

The actress who played late-night horror hostess Elvira has claimed she was sexually assaulted by late NBA player Wilt Chamberlain.

Cassandra Peterson, 70, who began portraying the famous horror figure in the 1980s, made the allegations in her tell-all memoir Yours Cruelly, Elvira: Memoirs of the Mistress of the Dark, released on Tuesday. 

She claims the former Harlem Globetrotter had forced her to perform oral sex on him. 

'When a 7-foot-1, 300-pound man has his hand wrapped around your neck, there’s really not a lot you can do,' Peterson wrote.

She also references Chamberlain's memoir where he detailed his history of romantic relationships with women - which he claimed to be 20,000. 

'I had to wonder how many of those women actually consented to having sex with him,' Peterson added.

In her memoir, Peterson discussed several anecdotes about her life involving romantic relationships and her other Hollywood experiences. Peterson performs her new show "Elvira, Mistress Of The Dark" at Knott's Scary Farm at Knott's Berry Farm on September 21, 2017 in Buena Park, California

Peterson also wrote about her experiences with other male celebrities when she was a Vegas showgirl such as biting the lip of Andy Williams who allegedly tried to forcibly kiss her, and claims Tom Jones accidentally sent her to the emergency room following an internal injury sustained while they had sex.  

The former mistress of the dark also revealed that she is now dating a woman.

The cult horror star had kept her 19-year-relationship with female trainer Teresa 'T' Wierson secret until now because she said she feared alienating fans. But when writing her memoir, she decided she wanted to be fully open.

'I’m glad to have it out there,' she wrote. 'I mean, it does worry me. I have moments where I go, ‘Maybe people won’t like me anymore’ and ‘Maybe I won’t get work anymore.’ 

'It’s ridiculous to think that, but I have friends who are gay and have come out of the closet and it affected their work, relationships and their life. So it’s not so far-fetched to be worried. But on the other side of that, it’s so draining keeping it a secret. It’s not good for you, it’s not good for us. It sucks the energy out of you.'

Peterson explains that when she first noticed Wierson at the gym, she mistook her for a man. 

 'Often, when I was doing my preworkout warm-up on the treadmill, I couldn't help noticing one particular trainer — tan, tattooed, and muscular — stalking across the gym floor, knit cap pulled so low over his long brown hair that it nearly covered his eyes,' she wrote, according to People.

'A typical sexy bad boy, he was unaware he was so charismatic that he'd garnered his own unofficial fan club. Watching him from the safety of my treadmill made my heart beat faster and the time pass much more quickly.' 

Although in a same-sex relationship, Peterson still claims she is attracted to men still.  

Peterson was formerly married to film producer Mark Pierson, who worked on a few of her projects, for 22 years and the couple had a daughter together in 1994.

Following their divorce in 2003, Peterson then became romantically involved with her now girlfriend Wierson. 

In addition to her romantic history, Peterson went into depth about other entertaining aspects of her life. 

One of Peterson's earliest projects was a stint on the popular 70's television series Happy Days

She was born and raised in the small-town of Manhattan, Kansas where she desired to be a horror film star after falling in love with the genre when she was eight.

When she was 18-months-old she suffered third-degree burns after accidentally tipping a pot of hot water onto her which left permanent scars on her body.

When she hit 14, she became a party girl as she started going to nightclubs and experimenting with substances such as alcohol and drugs.  

She also was a teenage groupie at 18 and began working as a Vegas showgirl shortly after where she met and entertained several male celebrities. 

Her career began in Hollywood when she joined a comedy acting troupe and began developing her acting skills.

Peterson became the iconic 'Elvira' after auditioning to become the hostess of a late night horror show. 

Following her appearance, she became the iconic B-movie queen of horror of the 80s as it spawned several movies and television programs surrounding her character.
