Porsha Williams is having a major issue with her fiancé Dennis - he put an offer down on a house without consulting her. And dropped a down payment, that he withdrew from their "joint" account.

And Dennis plans on using "their" money to buy the house.

Dennis is currently selling his condo, and living in Porsha's Atlanta mansion. But the couple planned on moving soon after PJ was born, and buying a bigger new house.

Well Dennis found the house without Porsha. In fact, he never even told her that he was going to be out looking, nor did he ever consult his fiancé.

Nonetheless, Porsha's fiancé and de facto business manager, dropped more than $50,000 on the house as a down payment. $50K that was withdrawn from their joint account.

Here's what one of Porsha's friends told MTO News, "Dennis is so disrespectful. How do you go any buy a house with someone else's money, and not even talk to them about it."

According to our snitches at Bravo, the entire incident will unfold on Porsha & Dennis special airing tonight on Bravo.

According to the Bravo blog a few weeks ago, "Parenthood is definitely a big adjustment for any couple, but it looks like The Real Housewives of Atlanta's Porsha Williams and Dennis McKinley are loving their new roles. The first-time parents, who announced they are getting married this New Year's Eve, have not been shy about sharing photos of themselves loving on their sweet new daughter, Pilar Jhena McKinley, who was born on March 22. Porsha has shared that seeing Dennis and Pilar together has her feeling "blessed and highly favored" and Dennis has shared sweet photos of his baby girl on Instagram Stories.

Still adjusting to having a baby in the house can tire out even the most adaptable of parents — and the McKinleys are no exception. On April 17, Porsha posted a photo of Dennis passed out, clutching Pilar's pillow. "Um sir that is [Pilar's]," Porsha captioned her photo, adding the telling hashtags: "#PoThang, #NewDad, #Exhausted, #GoodPapa, and #HeGoneGetMe." Hey, he's entitled to catch some z's whenever he can as a new dad!
