Met Gala 2015
Met Gala 2015: Justin BieberReuters

Justin Bieber is famous for flouting rules, and this time, his partner-in crime was none other than Cara Delevingne. Their recent 'crime' was to take a selfie at the Met Gala, in spite of the authorities banning it this time at the event.

Vogue's editor-in-chief, Anna Wintour, had apparently banned the Met Gala attendees from taking photos and uploading them on social media. But the "Never Say Never" singer did what he does best, and took not one, but two selfies – one with Delevingne and another with Lady Gaga.

Well, no one can blame either of the ladies for breaking the rule, because the Canadian singer looked dapper in a custom-made Balmain blazer with golden dragon embroidery that went well with the night's theme: 'China: Through The Looking Glass'.

But JB isn't the only star to roll his eyes at the invitation instruction that read, "The use of phones for photography and social media will not be permitted inside the gala." Katy Perry, Lady Gaga and Kanye West were among the few who indulged in taking pictures.

So, either they had ignored that tiny bit of information, or just didn't care enough. Whatever the reason, fans are happy to see the pictures and happily liked and shared them on social media apps.
