Ne-Yo’s ex-girlfriend is suing the singer for defamation after he breached an agreement not to go public with information about their relationship.

In 2009, Jesseca White and Ne-Yo reached a $575,000 settlement agreement stemming from White’s pregnancy while the two were dating. White gave birth to a baby boy named Chimere in 2005, and Ne-Yo was originally listed as the child’s father, but his name was later removed from the birth certificate when White revealed that the child wasn’t his.

In September 2012, Ne-Yo did a Behind the Music special on VH1 in which he discussed his relationship with White, breaking the confidentiality clause of their agreement.

Now White has hired Gloria Allred , who often takes on high-profile discrimination cases, as her attorney. Allred is claiming that Ne-Yo painted an unfair picture of her client, portraying her as a liar who broke Ne-Yo’s heart and disappeared.

Allred said White has been “beset by nausea, vomiting, and hair loss” because of what Ne-Yo said about her in the special.

White has asked the “One in a Million” singer — whose real name is Shaffer Chimere Smith — to settle the matter outside of court, but he has yet to respond.

Ne-Yo has said that he wasn’t using the special to bash his ex-girlfriend. He wrote:

Ne-Yo now has two children with fiancée Monyetta Shaw . Their daughter, Madilyn Grace Smith, was born November 12, 2010. The couple’s son, Mason Evan Smith, was born less than a year later on October 9, 2011.
