In case you missed it, the 2017 Met Gala took place Monday night. Apple was there as a sponsor, but it didn't break any iPhone 8 news, and sponsor Warner Bros. didn't break any news on the upcoming "Justice League" movie. The only thing broken, it appears, was the Met Gala's "no selfie rule," which was infringed by none other than Kylie Jenner, plus several other celebs.

The annual Costume Institute Benefit at New York's Metropolitan Museum of Art marks one of the year's biggest celebrations of art and fashion. This year's theme was Kawakubo/Comme des Garcons, which refers to "avant garde" or over-the-top clothes that cost as much as your car. (Check out some shots from last year's tech-themed event in the gallery below.)

Anna Wintour, editor-in-chief of Vogue, instated a ban on all social media at the Met Gala gala in 2015. But while organizers of the gala asked that no one post selfies, 19-year-old Jenner disregarded the "no selfie" policy yet again -- just like she did last year.

That's right, celebrities dressed in high-end fashion you want the world to see. Kiss your Snapchat, Instagram, Periscope goodbye, and don't even think about going Facebook Live. But why such a restriction for such a high-profile event? The Costume Institute declined to comment.

It makes sense an event like this would want to maintain exclusivity and provide photo ops for distributors like Getty, but could a selfie really hurt? But really, who's going to stop Beyoncé from snapping a shot of her stunning dress?

Selfie bans are not unheard of. Two years ago, for example, the Cannes Film Festival clamped down on red-carpet selfies, saying all those smartphone snaps slow things down.
