Katy Perry, Justin Bieber, Cara Delevingne and Kim Kardashian all flouted the imposed selfie and social media ban at the 2015 Met Gala earlier this week, along with countless others – and who can blame them? It was after all, one of the biggest red carpet events of the year. But according to reports, Anna Wintour is not amused – and wants all of the 'illegal' posts taken down.

"Anna is very aware of all the celebrities who ignored her request," a Vogue insider told the press. "She does not know what she's going to do yet but she's deciding."
