Up in Smoke: How Some Stars Broke All the Rules at the Met Gala

The event occurred Monday night at the Metropolitan Museum of Art.

Some of the A-listers at the Met Gala Monday night clearly didn’t abide by the old “pics or it didn’t happen” phrase, after showcasing a blatant disregard for the event's rules with bathroom smoking and mirror selfies.

At one point, stars like Kim Kardashian, Diddy, Kylie Jenner, Frank Ocean, Paris Jackson, Kendall Jenner and A$AP Rocky — among others — all packed into the ladies room for an epic bathroom selfie during the party at the Metropolitan Museum of Art.

The organizers of the event have a strict “no social media” policy once the attendees get inside the venue, a rule that was implemented in 2015 by Vogue editor-in-chief Anna Wintour.

It wasn’t just the selfie sin that was committed, as Bella Hadid was seen smoking — forbidden by New York City law — in an Instagram photo posted by Paris Jackson, which featured the pair sitting on the bathroom floor with Ruby Rose and Lara Stone.

In another Instagram image, designer Marc Jacobs and Francis Bean Cobain were also puffing on cigarettes in ladies room photo that also featured Cobain's mother, Courtney Love.

Rita Ora posted on Snapchat a photo of herself and Mr. Robot star Rami Malek, who was having a smoke in the women's restroom.

Lighting up is strictly prohibited in New York City following former Mayor Michael Bloomberg's Smoke Free Air Act of 2002, which banned the practice in most workplaces, including bars, restaurants, clubs, offices and other public areas.

Since, the Metropolitan Museum of Art is a public museum, it falls under the guidelines and smoking bans.

It was followed nine years later by a new law that restricted smoking in the Big Apple's national parks, beaches and pedestrian areas.

Both The Met and the City of New York did not immediately respond to InsideEdition.com's requests for comment.
