Celebrities, who routinely get away with things normal humans do not get away with, are getting away with smoking at the Metropolitan Museum of Art. But the museum itself is under fire from the city's Department of Health.

Frances Bean Cobain, Marc Jacobs, Dakota Johnson, Rami Malek, Paris Jackson, P. Diddy, and Bella Hadid were among those who selfie'd (also banned!) from the bathroom of the museum during the Met Gala. C'mon, famous people, have some respect for the art, the event, and the institution. It's pretty bad when even Courtney Love won't partake (or at the very least she was smart enough to hide her cigarette when this photo was snapped):

After the posts showed up on social media, the city’s health commissioner, Dr. Mary Bassett, wrote a letter to the higher ups at the museum. According to the Daily News, she reminded them of the city's smoking ban (which has been in effect since 2003), noting:

"We were dismayed to read reports that some celebrities chose smoking as their fashion accessory and flagrantly violated New York City’s smoking laws. There is also no safe level of exposure to secondhand smoke. All visitors to public places deserve protection from secondhand smoke, including people who are visiting places like The Met."

Bassett, a former smoker herself, also worried "about how images of these celebrities smoking — which were widely shared around the world via social media — will affect youth smoking rates."

One museum donor told the NY Post, “As a donor to the Met, I was so insulted to see all these celebrities smoking and taking selfies of themselves in the bathroom. Mostly, it’s disrespectful to the art collection, which needs to be kept 100% smoke-free. I would honestly like to see these people fined by the city.” The fine for smoking about 100 bucks, or the cost of one sequin on one of the above gowns.

The Met has yet to comment on their smoking guests, but the Dept. of Health has already offered a solution: "For next year’s event, DOHMH is able to send inspectors or provide other assistance to improve compliance, should The Met desire this support."
