It's much ado about a cupcake between Mama June Shannon and Sugar Bear's fiancee.

In TooFab's exclusive sneak peek at Friday's episode of "Mama June: From Not to Hot," Mike Thompson's new flame -- and current wife -- Jennifer vents to one of her friends about June's behavior. ICYMI: the two got into it last week after Alana "Honey Boo Boo" Thompson brought a sweet home with her after dinner with her father and Jen, threatening June's healthier lifestyle.

"June showed her ass!" Jennifer tells her friend Miss Janice, who used to be married to Shannon's brother. It's a small world after all!

"She ripped my head off over a cupcake because she's on a stupid diet," Sugar's lady explained.

While June told Jennifer she was "not the mother" and was "never going to be anything to Alana," Miss Janice talked her down.

"When you marry Mike, you not only marry the good side of him, but the bad side too, which is going to be June because of Alana," she said. "Kill her with kindness. The kinder you are to her, the worser she hates you for it."

According to the official synopsis of Friday's episode, "June's weight blows up when her emotional eating gets out of control" as "tension with Jennifer escalates." Shannon's secret junk food stash is also exposed as she attempts to lose more weight before a breast life and tummy tuck. "Mama June" From Not to Hot" airs Fridays at 10pm on WEtv.
