Nida was sentenced to aneight-year prison sentencein July 2014 after pleading guilty to bank fraud and identity theft in May 2014 (the same year he and Parks split). However, in late July, he was released from the Fort Dix Correctional Facility in New Jersey to a halfway house in Philadelphia, according to online records from the Federal Detention Center (FDC).

He’s currently engaged to Sherien Almufti.

Back in December, Parks told PEOPLE that she wasn’t interested in reconciling a romantic relationship with Nida.

“We have two beautiful sons together,” she shared. “I’ll always be grateful for that. I’m hopinghe will get married to whomever he is engaged to, honey, and he will be out of my hair.”

As for their boys?

“They are definitely full of personality. Totally opposite but both hilarious,” she said. “They are third grade and kindergarten and with all kinds of sports and after-school activities on their schedule — that is a job in and of itself!”
