Apollo Nida may be stuck behind bars in a New Jersey prison, but the former “Real Housewives of Atlanta” star isn’t letting that stop him for publicly bashing his fiancée’s ex-husband. In an Instagram post, Apollo called out Sherien Almufti’s ex, Derrick Copes, for supposedly falling behind on child support.

On Thursday, a few days after announcing his engagement, Apollo’s team posted a letter stating that Copes allegedly owes Almufti child support for their daughter. “Do you know the difference between a bucket of KFC chicken & Derrick Copes?? KFC CAN FEED A FAMILY OF 4 while Derrick can’t even pay current or back child support from 2013,” the caption read. “#thenidateam #paperwork don’t lie !! this is a high mountain this guy is attempting to climb on. Don’t be a groupie be a man take care of your child oh sorry children ??? To be continued!!! #THENIDATEAM!!”

Almufti also took to Instagram to bash her ex, posting a text message conversation she had a with a friend about a recent interview Copes did. In one of the messages, Almufti’s friend said it was “funny” that Copes said he had just recently stopped paying child support. “Girl wish you were here with me … Sipping Martini’s and having dinner with the family. Ex is an ex for a reason,” Almufti responded to her friend.

On Tuesday, Copes told Radar Online that he wasn’t going to give his ex-wife money for their 8-year-old daughter until she stopped taking the child to see Apollo in prison. The former Bravo star is serving an eight-year sentence for fraud at New Jersey’s Fort Dix Federal Correctional Facility.

“I’m not giving her child support right now because she’s taking my daughter to prison and I have asked her numerous times to stop doing that,” Copes told the outlet. “My daughter is eight years old, she is not happy to go into a prison. If you want me to give you money, I will, but at the same time you have a responsibility to our daughter.” He added: “If Apollo is in my daughter’s life, that’s no problem — but don’t take her to prison.”

Apollo announced he was engaged to Almufti earlier this week. The pair have been dating for at least two years. The engagement news came weeks after “Real Housewives of Atlanta” star Phaedra Parks announced that her divorce from Apollo had been finalized.
