There’s more baby mama drama in store for Future in 2016. The rapper has publicly blasted his ex, Ciara, over custody of their son, Future.

The couple, who ended their relationship in August 2014, has been involved in a custody battle for the past year-and-a-half, according to Future.

But on Monday, he took to Twitter to express his frustration. “This bitch got control problems,” he wrote, adding that he has to pay $15,000 per month in child support.

“I gotta go through lawyers to see babyfuture…the fuckery for 15k a month,” he said, adding, “I jus want babyfuture that’s all.”

Future claims that he’s been privately dealing with the issues, but finally decided to go public with it. “I been silent for a year & a half..I ran outta patience,” he said.

The couple called off their engagement amidst reports of Future’s infidelity. “It clearly didn’t work out. But I have the greatest gift, the greatest joy of my life is my son,” Ciara previously told “The Breakfast Club.” “I feel like everything in life happens for a reason and my son has been the greatest gift that God has given me in my life, and been the most game-changing thing that has happened in my life in a necessary way.”
