• Ne-Yo's wife, Crystal Renay, filed for divorce in Atlanta after claiming he has been cheating on her
  • Renay said their marriage is "irretrievably broken with no hope for reconciliation"
  • She seeks primary physical custody, joint legal custody, child support and alimony

Ne-Yo's wife, Crystal Renay, filed for divorce after alleging that he had been unfaithful to her in their marriage.

Renay wants to make her separation from the R&B singer official. She filed for divorce in Atlanta earlier this week, claiming that their marriage is "irretrievably broken with no hope for reconciliation," according to the divorce documents obtained by People.

In her filing, Renay also alleged that she and the "So Sick" singer got separated since July 22, and Ne-Yo "recently fathered a minor" with his "paramour," Page Six added.

According to her, she has been taking care of their three children —sons Shaffer, 6, and Roman, 4, and a 1-year-old daughter— and she's seeking primary physical custody, joint legal custody, child support and alimony.

Ne-Yo and Renay's reps did not immediately respond to requests for comment, according to People.

Before her filing, the model took to Instagram and posted an update about their marriage, claiming that her husband had been cheating on her for eight years.

"[Eight] years of life and deception. [Eight] years of unknowingly sharing my life and husband with numerous women who sell their bodies to him unprotected … every last one of them," Renay, 36, wrote in a since-deleted post. "To say I'm heartbroken and disgusted is [an] understatement. To ask me to stay and accept it is absolutely insane. The mentality of a narcissist."

She also said she would no longer lie or pretend and hinted that she was moving on from her marriage by choosing herself and happiness.

"I choose me, I choose my happiness and health and my respect," she continued.

She said that aside from their "three beautiful children," her marriage to the Grammy winner was "nothing else" but "wasted years and heartache."

The "Time of Our Lives" singer responded to his wife's post on Twitter by asking the netizens for respect and privacy. He also said that he would work on the issue privately.

"For the sake of our children, my family and I will work through our challenges behind closed doors," he tweeted. "Personal matters are not meant to be addressed and dissected in public forums. I simply ask that you please respect me and my family's privacy at this time."

The couple had an on-again, off-again relationship. They got married in 2016 and decided to get a divorce four years later but reconciled after a month. They renewed their vows in a lavish ceremony at Resorts World Las Vegas in April.
