Contrary to what most people around the world likely think, Kate Plus 8 is still a TV show.

It airs new episodes and everything.

Similarly, despite neither its star nor her estranged husband being in the news very much anymore, Kate Gosselin and Jon Gosselin remain at odds.

That's putting it mildly.

This remains one of the most volatile and ugly celebrity breakups in history, and years later, may even be getting worse if not better.

Sad case in point:

According to police in Wyomissing, Pennsylvania, a call was made on Tuesday afternoon regarding a Custody dispute between the ex-spouses and reality TV co-stars.

As reported by TMZ, E! News and other outlets, cops were called to an orthodontist’s office around 1:10 p.m. due to a “verbal domestic dispute over child custody involving one minor (Female/13 years old)."

One of the controversial parents took their child to her appointment, but then the other showed up and an argument broke out over who would be driving her home.

A Wyomissing Police Department spokesperson didn't offer too many details, but did reveal to Entertainment Tonight:

“The call came in at 1:10 this afternoon for a verbal domestic argument … over the custody of one of their 13-year-old daughters."

“No one was arrested and the daughter did go home with the father after she expressed that was her desire to do."

Married for a decade until their divorce in 2009, the Gosselins rose to fame as the lead cast members on Jon & Kate Plus 8.

They starred on the series along with their eight children.

Twins Mady and Cara recently turned 16; Jon and Kate's sextuplets Aaden, Alexis, Collin, Hannah, Leah and Joel are 13.

Tension has existed between Jon and Kate ever since their split, but they have operated under the same custody arrangement for seven years now.

Details are mostly kept under wraps, even as they feud about this in public; Jon and Kate share custody in some complicated fashion.

Kate recently made negative headlines after an episode of Kate Plus 8 aired in which the sextuplets celebrated their 13th birthdays.

All except Collin, that is.

The young teenager was missing because he’s in some mystery facility being treated for "special needs" by so-called "behavior specialists."

This is perfectly fine and maybe even healthy for the child, but Kate has seemingly just gone on with her life and her show.

Fans have accused her of essentially shrugging over the fact that one of her sons isn't part of the family, not even for milestone occasions.

Jon, meanwhile, has done very little for years.

Waiting tables, DJing and working other jobs to pay the bills, he did sort of perform at a strip club this spring, so that's something, we guess.

Look, both Jon and Kate are very annoying.

We don't know exactly how their latest tiff was left, but, as always, we hope they can keep things as amicable as possible moving forward.

There are quite a few kids in the picture here. One would think that would be the determining factor in behaving like adults, but ...
