Jackson previously criticized Keke Palmer over her outfit at an Usher concert.
In July, Palmer watched Usher perform in Las Vegas while wearing a body suit and sheer dress combo.
At one point, the "Climax" singer brought Palmer onstage and sang "There Goes My Baby" to her in front of the audience.
Jackson took to X, the platform formerly known as Twitter, to criticize his partner's choice of outfit in a series of since-deleted tweets.
He first replied to a clip of the performance, writing: "It's the outfit tho.. you a mom."
Jackson continued; "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. This is my family & my representation. I have standards & morals to what I believe. I rest my case."
Palmer appeared to respond to Jackson with a tweet of her own.
She wrote: "One thing is certain and one thing is true, IM A MOTHA, through and through! To all my mom's out there, how did your baby change you??"
Palmer added: "Mine empowered me! On such another level, my perspective changed because when my baby is good I'm GREAT! Look at that face! Gratitude galore."
In August, Entertainment Tonight reported that the pair had broken up after the drama over Palmer's outfit at the Usher concert.
However, Jackson responded in a since-deleted tweet: "I haven't spoken to anyone about anything or gave permission to anyone to speak for me.. So all these sites & post about me making any type of statement is false.."
Entertainment Tonight reported Thursday that in her court filing, Palmer said that she and Jackson ended their relationship last month.
