P.P. Arnold, the soul singer who performed as an Ikette with the Ike & Tina Turner Revenue, is opening up about her life in an upcoming memoir -- and she makes a shocking allegation against Ike Turner.

While discussing her upcoming memoir Soul Survivor, Arnold tells The Telegraph, that Ike Turner once trapped her in a room and raped her in the mid-1960s.

After the alleged sexual assault, Arnold struggled with her anger at Turner, who died in 2007 at the age of 76.

"What can I say? It was awful. I despised Ike on that level, but I didn't know how to express myself," said Arnold, now 75.

"I was told Tina wanted to get rid of me because Ike was after me," Arnold added of Ike's then-wife, Tina Turner.

"If I had run to Tina or called my parents, it would have meant I would have [had] to come home."

According to her interview with the Telegraph, she and her husband David were forced to get married after an attempted abortion with a sterilized coat hanger didn't work.

She went through with the birth and had her son Kevin at 15 years old. Later, at 17, she gave birth to her daughter Debbie.

Arnold says she also had a "deep anger" with her husband's violence, but that she "dealt with it."

"Sadly it was the way it was back then. I think it's a lot to do with slavery and how that affected the black man's psyche," the "Angel of the Morning" singer said.

Arnold tells the the outlet that she eventually left the Ikettes after Rolling Stones frontman Mick Jagger convinced her to move on
