Singer suing Future for slander, libel and calling her "bad mother

Ciara is suing ex-lover, Future for allegedly calling her a "bad mother" as well as insulting her relationship with NFL star Russell Wilson all to promote his music.

According to legal documents obtained by TMZ, the 'Body Party' singer claims Future wrongfully discussed a now infamous photo of Wilson pushing Ciara and Future's son in his stroller. "She probably set him [Russell] up. You letting them catch that photo. Leave my son out of all the publicity stunts," Future had said about the photo in the interview.

Ciara also cited several other interviews, but she's also pissed about her baby daddy's Twitter rant in January when Future said, "This bitch got control problems ... I gotta go through lawyers to see baby future ... the f***ery for 15k a month."

In the suit, Ciara says she goes out of her way to make sure Future sees their son -- and says they've had at least 19 visitations (some spanning several days) since December 2014.

TMZ even posted a video of Future and his son in Los Angeles while Ciara was on vacay with Wilson last week and thought it was a sign they were settling their differences, but that's clearly not the case.

Ciara believes Future's comments were said with malice. She's suing for slander and libel, wants all his nasty tweets deleted, and wants him blocked from saying anything about private family matters regarding baby Future ... in the future.
