Keke Palmer Stands by Usher Outfit Choice After BF Throws 'Mom' Shade

Keke Palmer's boyfriend isn't gonna get a rise out of her -- at least publicly -- after he insinuated her choice of attire for an Usher concert wasn't appropriate for a mom.

The "Nope" actress is telling the world she had no regrets following the very public remarks made by Darius Jackson, the father of her son, regarding her outfit while attending Usher's Vegas residency last weekend.

Keke doubled down on her sexy wardrobe selection in a recap on IG ... that made no mention of Darius whatsoever.

She posted a pic in THE outfit, and said, "I wish I had taken more pictures but we were running late! I am telling y'all right now, if you haven't seen @usher YOU MUST GO!! HE WAS SO FABULOUS!!"

Referring to Usher, Keke added ... "Where is that pic of us all together with the King himself??"

The "king" Usher sided with his VIP guest, or at least shouted her out ... thanking her for attending his show, not to mention giving his Vegas residency yet another viral moment!!!

Darius was royally pissed off Wednesday when fans ripped him for being extra critical of Keke's sheer 'fit. He said, "We live in a generation where a man of the family doesn’t want the wife & mother to his kids to showcase booty cheeks to please others & he gets told how much of a hater he is."

As of Thursday, Keke and Darius don't follow each other on Instagram.

Hey Alexa, play "Moving Mountains" by Usher. 🎶
