Ne-Yo's wife, Crystal Renay Smith, is accusing the singer of cheating on her.

"8 years of lies and deception. 8 years of unknowingly sharing my life and husband with numerous of women who sell their bodies to him unprotected... every last one of them!" she wrote in a scathing post on Instagram, as she asked the public to "please stop sending me videos or information of him cheating".

The model, who shares three children with the So Sick hitmaker, said she was "heartbroken and disgusted".

"To ask me to stay and accept it is absolutely insane. The mentality of a narcissist. I will no longer lie to the public or pretend that this is something it isn't. I choose me, I choose my happiness and health and my respect."
