Ciara Sues Former Fiance for Slander, Defamation and Libel

She is alleging the father of her son committed slander, defamation and libel.

— -- Ciara has filed a $15 million lawsuit against her former fiancé, Future.

In paperwork obtained by ABC News, the singer accused the rapper of committing libel, slander and defamation. In addition to money, she wants him to delete tweets he's written about her, issue a retraction, and refrain from publishing private information about her going forward.

The two had been dating for more than a year when they announced their engagement in late 2013. A few months later, they welcomed their son, Future Zahir Wilburn. They split in September 2014.

In her lawsuit, Ciara, whose real name is Ciara Harris, also accused Future (real name: Nayvadius Wilburn) of falsely accusing her of keeping their son away from him. Her lawyers also pointed out that they have sent several cease and desist letters to Future's team in the past.

"The false and defamatory statements tweeted by [Future] were published online for the purpose of assassinating the name, reputation and character of [Ciara], [Ciara's] reputation as a good mother, diminishing the value of [Ciara's] brand and impairing [Ciara's] career as an entertainer," her lawyers wrote.

Reps for Future and Ciara have not responded to requests for comment by ABC News.
