Pro Green, real name Stephen Manderson, and 26-year-old Millie married in 2013 and their unlikely romance has been the target of constant split reports.
Although the 31-year-old rapper insists there's no problems, he revealed how they make their relationship work. He told The Sun: "We both see the same therapist and, yeah, we have sat down with her together.
"Sometimes it's easier to understand things when they come from the person who is completely removed from the situation – it's one of the most constructive things I do in my life."
He's preparing to release his autobiography, in which Pro details his first major fall-out with former Made In Chelsea star Millie – blaming lack of alcohol.
"We were at each other's throats," he said. "We thought we f*****g hated each other. Then ate normally and had a glass of wine and it was fine. It was the lack of sugar, 100 per cent. I'm never doing that again."
And Pro blasted claims that his wife is too posh for him, claiming that he earns more money than her.
He added: "I make more money than Millie. If money makes you posh, then I'm posher than her."
