Apparently Ne-Yo fathered a child outside their marriage...
According to TMZ the divorce docs filed by Crystal listed the marriage as "irretrievably broken with no hope for reconciliation" and listed the date of separation as July 22, 2022.
The petition also accuses Ne-Yo of committing adultery and fathering a child with another woman.
