Her boyfriend, fitness instructor Darius Jackson, was apparently not a fan of the footage showing Palmer in a fitted, black bodysuit with a sheer overlay dancing with Usher as he sang to her.
"It's the outfit tho..you a mom," he tweeted.

There was backlash causing Jackson, 28, to explain his position.
"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," he wrote in another tweet. "This is my family & my representation. I have standards & morals to what I believe. I rest my case."
Palmer gave birth four months ago to Leodis "Leo" Andrellton Jackson, whom she shares with Jackson.

The 29-year-old "Nope" star and Jackson are not married, and on Thursday, it appeared he had deleted his Twitter account.
CNN has reached out to reps for the couple for comment.
