The annual Met Gala would the perfect place to watch Hollywood stars walk the red carpet with their kiddos. So why don’t we ever see celebrities bringing their children along as dates? Well, the answer is simple: the glamorous and highly anticipated event only allows attendees over the age of 18.

This may come as surprise to Met Gala fans considering the high-profile event was once a place for celebrity kids to party like the adults. In fact, the gala — which has been hosted by the Metropolitan Museum of Art’s Costume Institute every first Monday of May since it’s debut in 1948 — just banned attendees under the age of 18 following the 2017 celebration.

Last year, organizers of the lavish gala — chaired by Vogue editor-in-chief Anna Wintour — confirmed on the official website that people under 18 years old would be unable to attend ahead of the 2018 event. “It’s not an appropriate event for people under 18,” an event coordinator explained to The Hollywood Reporter last May.

Although there was no exact reason why the ban was put into place, many assume that The Costume Institute cracked down after Elle Fanning was photographed toasting with a beverage that looked like a glass of white wine during the ball in 2017. Organizers received a ton of backlash considering the Maleficent actress was only 19 years old at the time.

Although it caused quite the controversy, her representative insisted to Daily Mail that she wasn’t drinking any type of alcohol while participating in the toast. “Elle did NOT drink alcohol at the Met Gala,” the email sent to the outlet read. “The glasses were at the table before everyone was seated and she only participated in a toast.”

Before the age limit was instituted, tons of celebrity kids have hit the Met Gala red carpets with their parents. In 2016, Will Smith‘s kids, Jaden Smith and Willow Smith, attended the event when they were just 17 and 15, respectively. One year later, Sylvester Stallone‘s daughter Sistine Stallone strutted her stuff in a sparkly silver gown at the age of 18.

Although the organizers of the prestigious event take the age limit seriously, there is one loophole: A minor can attend if their parents are in attendance or invited, according to E! News.
