Monica Arnold announced a few weeks ago that she and her husband Shannon Brown were divorcing. Now MTO News has some tea.

One of the women that Shannon was cheating on Monica with is now pregnant, and she's claiming that Shannon is the father. And according to Monica's friend - that was the straw that broke the camel's back.

Monica's GF explained, "Its one thing for your husband to have a side chick. But [Shannon] was like out here trying to have a whole baby on the side."

Mo's friend continued, "What is going on with all these men having babies with their side chicks - that must be the 'wave' these days."

While paternity hasn't been established yet, and it's not clear whether the baby is in fact Shannon's - Monica had enough.

Monica's pal told MTO News, "Their marriage is over. Hopefully they can co-parent effectively."

Monica's divorce is playing out in real time - on the new season of the VH1 hit show TI & Tiny's Friends & Family Hustle, Mondays at 9PM on VH1.

Here's a scene from it:

At the end of March, Monica served Shannon with divorce papers. The singer filed the paperwork earlier this month in Atlanta. Monica and Shannon have a 5-year-old daughter named Laiyah together, and she has 2 sons from a previous relationship with rapper Rocko.

So far there are no details on whether she's seeking child or spousal support ... but we've learned Monica was unsuccessful in sealing the divorce docs.

The couple wed in 2010, but there was speculation they were separated in October 2018 ... until she shared a loving photo of the 2 together on Instagram. She hasn't been wearing her ring in Instagram photos for a few weeks though.
