Marla Maples bickers with children's book author over seats at movie theater

Trump ex Marla Maples will not be the nation’s First Lady, but she apparently has no problem exercising executive privileges.

The second wife of the President-elect was involved in a “verbal altercation” with children’s book author Deborah Gregory at a movie screening when, according to our sources, there was disagreement over her seating assignment.

Spies at a recent Upper West Side screening of the Pharrell Williams-produced film “Hidden Figures” tell us

that the 53-year-old Maples and a friend grabbed a pair of seats that had been claimed by Gregory, whose best known for penning the popular “Cheetah Girls” book series and co-producing the Disney Channel’s adaptations. We're told that Gregory and her pals were previously settled into the seats at the center of the dispute, but walked away for a few minutes to take photos with fans and event photographers.

When Gregory and two friends returned just before show time, Maples had hunkered down and gotten comfortable. We’re told that the Brooklyn-born author tried diplomatically to explain to Maples that there were assigned seats for this particular event — and those were hers — but Maples wasn't having it.

“Deborah told Marla politely that those were her seats, but Marla refused to move,” according to our cinema snitch. “(Marla) said. ‘Oh my God. These are my seats!’”

When all was said and done, we're told that Maples, who was married to Donald Trump from 1993 to 1999 and who is the mother of the President-elect's youngest daughter Tiffany Trump, hashed out a peace accord with Gregory. Gregory confirmed the altercation, and laughed it off.

"We're all good!" Gregory said, adding that in the dark theater she didn't recognize Maples, whom she calls "a sweetheart," insisting that she was glad to find other seats nearby. "We had a grand old time and even took a picture together afterwards."

Maples could not be reached for comment.
