Future’s comments about his ex and mother of his son, Ciara, will likely cost him. She’s suing the rapper for $15 million, claiming he’s publicly slamming her to benefit his own career.

In the lawsuit, Ciara cited a couple of incidents where Future either insinuated she's a bad mother or brought up her relationship with NFL star Russell Wilson negatively.

In past radio interviews, many of which Ciara brought up in the libel and slander lawsuit, Future blasted her for bringing their son to the Seattle Seahawks player’s training camp practice. He also got mad that Wilson was photographed pushing their son in a stroller, calling it a “publicity stunt” and accusing Ciara of setting up a photo op.

In what was likely the last straw for Ciara, she also mentioned his Twitter rant from last month, where he wrote she has “control problems” and that he has to “go through lawyers to see babyfuture,” adding, “the f***ery for 15K a month.”

TMZ reports Ciara claims in the lawsuit that she’s more than willing to share visitation with their son, citing 19 times Future has had him.

She’s asking her ex not to mention private family matters publicly from now on.
