If there was one place to be seen at the 2017 Met Gala, it was the video booth!
Everyone from Celine Dion to Jaden Smith and his dreads rocked up to the impressive set-up at the glitzy New York event.
While Perry started off with her back to the camera, the "Chained to the Rhythm" singer then swung around to show off her much-talked about Maison Margiela number, with dramatic and somewhat spooky music playing to match her bold look.
Vogue magazine editor Anna Wintour kept things simple, standing in one spot in her sparkly Chanel gown, while Smith was anything but still as he pranced his way around the booth wearing Louis Vuitton and clutching his dreads.
The 18-year-old son of actor Will Smith raved away to a trippy tune against alternating red, black and white backdrops.
Quantico star Priyanka Chopra pulled a classic over-the-shoulder turn against a pretty, floral background, while Serena Williams took her baby bump for a twirl in her gorgeous green Atelier Versace gown.
Sisters Kim Kardashian West and Kylie and Kendall Jenner, meanwhile, posed against the wall, with a cameo from rapper A$AP Rocky.
But it was Dion who slayed the booth, sashaying around in her Atelier Versace leather, cutaway outfit and origami-inspired headpiece.
Crawling along the catwalk, flashing her killer legs and even popping off her heel and holding it to her ear like a telephone, the Canadian singer could do no wrong with her fierceness!
Meanwhile, Girls star Lena Dunham had a pretty big surprise in store, thanks to her custom Elizabeth Kennedy dress.
