Another day, another messy back-and-forth spat between Gilbert Arenas and his baby mama, Laura Govan.

A day after she alleged that he slept with her sister, Gloria Govan, years ago — a rumor Gloria, her ex, Matt Barnes, and Gil all shot down — the former NBA All-Star took to his Instagram account to post a custody modification document over their four kids from court. Good grief.

And as usual when it comes to his ultra-messy baby-mama drama, No Chill Gil was on one, alleging that he has forked over $430,000 in child support since September 2015 — claiming Laura hasn't used any of it on their children.

Take a deep breath and read the following.

Um... wow. Not to be outdone, Laura used a sketch to seemingly illustrate her stance, labeling the post with the hashtag "#InRealLife."

Interesting. Well, Arenas, the self-proclaimed "#KingPetty," caught wind of that and again bit into his baby mama with another scathing IG.

The latter post had No Chill Gil saying everything from his baby mama dragging him to court 20-plus times to Laura allegedly violating every court order and trying to bait him into hitting her to slap domestic violence charges on him. 

Again... [Warning: This Instagram post contains profanity].

That line about her being lucky that he doesn't use his penchant for being petty to take their kids from her, though? No words.

When will this back-and-forth bickering ever end?

This might be the messiest baby-mama drama that an athlete has ever been involved in because there's no end in sight between these two.

We wish both sides could just learn to limit the fighting and concentrate on co-parenting their four kids in peace.

But judging from his self-titled "#KingPetty" and No Chill Gil IG name and Laura's willingness to implicate her own sister for a planned tell-all... we're not sure that will ever happen.

Welp. We're exhausted. Shouldn't they be, too?
