The well-upholstered pin-up turned up in a barely-there, pink Vivienne Westwood dress on Sunday — with the child holding her long train.
The bizarre move drew criticism from child advocacy groups who say little Adelaide Gault is too young to be used as a fashion accessory.
One guest told Page Six, "People were genuinely shocked.
"She didn't even have her own seat and had to sit at Pamela's feet, where people nearly stepped on her to get to the stage. The girl looked uncomfortable and kept tugging on her dress to get her attention, but Pamela waved her away.
"Pamela was telling people it was her daughter," the attendee said. "And, after she presented David LaChapelle with an award onstage, she shouted 'daughter' in front of the whole auditorium, and slapped her leg like she was calling a puppy. The girl rushed up to grab her train."
