Bethenny Frankel and Jason Hoppy's divorce is about to get even uglier.

The Real Housewives of New York City star is suing Hoppy for full custody of their seven-year-old daughter, Bryn, People reported.

Frankel reopened her divorce case and filed the documents on December 6, according to TMZ, and the pair is due in court in January 2018.

Less than two months ago, the exes reached a resolution in the harassment and stalking charges Frankel had brought against the father of her child after Hoppy was arrested in January 2017 for allegedly threatening her at Bryn's school.

A representative for the New York District Attorney's Office told People in late October that Hoppy had accepted a plea deal in which he'd be granted an Adjournment in Contemplation of Dismissal, meaning all charges will be dropped against him as long as he adheres to the rules and regulations of Frankel's order of protection against him for six months.

"We are pleased but not at all surprised that the charges were dismissed," Hoppy's attorney Alex Spiro told People in a statement at the time.

"It's clear from the trajectory of this case that her claims were not substantiated or credited, and the motive was questioned. Mr. Hoppy looks forward to moving on with his life and his daughter."

Frankel and Hoppy, both 47, announced their decision to call it quits on their marriage in December 2012 following several years of rumors their relationship was on the rocks.

Frankel reportedly filed for divorce in January 2013, and the paperwork was finalized in July 2016.

The Bravo reality TV star referred to her divorce proceedings with Hoppy as "torturous" earlier this year.

In August, Frankel reportedly admitted on The Real Housewives of New York City's Season 9 reunion show that she's had to deal with "torment" ever since splitting from her ex-husband.

She revealed the only way to potentially better the situation would be to have "zero contact" with Hoppy.
