The Met Gala isn鈥檛 just an excuse for celebrities to walk the red carpet. The event is actually a fundraiser for the Metropolitan Museum of Art鈥檚 Costume Institute and has been happening since the 鈥70s. The Costume Institute聽is home to some of the world鈥檚 most precious and famous clothing from history and culture and is the location of every year鈥檚 gala. This year, celebs shared a bunch of bathroom selfies聽that showed guests smoking in the bathrooms at the Institute, and that鈥檚 got members of the Met fuming mad.

This is where it's at and yes, that is indeed Catherine Deneuve XPG.

While fans loved seeing their favorite celebs hamming it up and having a smoke in the bathrooms at the gala, donors to the museum are expressing their outrage that this was even happening. An account in聽Harpers Bazaar has one board member storming out of the washroom when they saw what was happening, 鈥淚t is so disrespectful to the museum,鈥 the anonymous source was quoted as saying.

But why the commotion? According to the source, the collection at the Met needs to be free from pollutants in order for curators to maintain the fabric鈥檚 longevity. Some of the items in the Met collection are quite old and cigarette smoke could potentially damage the art on display.

With no word on what will happen (if anything) to the offending parties, we do see why donors to the Institute would be upset by the smoking in the washroom. Maybe next year organizers will set up a designated (outdoor) smoking area.
