It looks like Toni has gotten fed up with Lewis not paying child support for the former couple's two sons Denim and Diezel. She filed the lawsuit in Georgia back on Oct. 31.

She accused Lewis of not paying the $2,000 she is owed each month. She has requested a judge order Lewis to pay up as soon as possible.

Braxton and Lewis tied the knot in 1998. They officially separated 12 years later in July 2013. Check out the detailed documents of Toni's lawsuit here.

News of Toni's child support battle comes just as Trina is involved in her own messy split with her now estranged husband Gabe Solis. Fans of Braxton Family Values have seen Trina and Solis go back-and-forth after she filed for divorce multiple times. They even sought out professional counseling from the Braxton family's therapist, Dr. Sherri after she caught him having inappropriate relationships with other women online.

Word is that Trina has had enough of not being able to trust Solis while she continues to fight for their marriage. She was set to speak on the status of her marriage in a press conference earlier this month but cancelled at the last minute. Reports also say that Solis is demanding he gets half of Trina's assets in the divorce.
