50 Cent has filed a defamation suit against his former girlfriend who has accused him of rape and physical abuse, the New York Post reports.

The lawsuit that was filed in Texas on May 6 (Monday), states that Daphne Joy, whose real name is Daphne Narvaez, accused him of harming her to gain sole custody of their 11-year-old son Sire. The suit also claims she was named as an alleged sex worker in a lawsuit involving Sean “Diddy” Combs.

According to the complaint, Narvaez “retaliated” against 50, whose real name is Curtis Jackson, by posting “multiple defamatory statements” to Instagram that “falsely and publicly accuse Jackson of rape and physical abuse during their prior relationship, in a purposeful attempt to… destroy his personal and business reputation, harm Jackson’s commercial and business interests, negatively affect his custody case, and prevent him from seeing his minor son. Narvaez’s claims are false.”

The suit also claims that Narvaez’s post on Instagram has caused severe damage to his business reputation and that the custody case had made him the target of hate on social media. So far, the post has garnered more than 22,000 likes.

“I am tired of upholding and protecting an image to our son that you have never even earned. Let’s put the real focus on your true evil actions of raping me and physically abusing me,” Narvaez wrote in a post in March.

Reena Jain, 50’s attorney, issued a statement obtained by PEOPLE saying, “Despite being given ample opportunity to retract a false and malicious retaliatory accusation, Ms. Narvaez has shamefully chosen to interfere with her 11-year-old son’s relationship with his loving father by falsely calling him a 'rapist.'"

In 2013, 50 pleaded not guilty to charges of domestic violence and property damage levied at him in Los Angeles by Narvaez. The court ordered the rapper to turn in all of his guns. According to the report, 50 entered Narvaez’s L.A. apartment and destroyed furniture and other items.

50 is seeking more than $1 million in monetary damages, claiming he was subject to “a barrage of horrendous online comments,” and that Narvaez shared the post “out of sheer hatred and ill will toward Jackson.”
