Because we’re fashion magpies, we found out that Gigi’s fancy frock is from the brand spanking new Balmain X H&M campaign, which she starred in alongside Kendall and Kylie earlier this year. “Now you can just enjoy yourself”, she continued before launching into a rendition of her hit “I Kissed a Girl”. I’m talking about all the assistants here. “And you feel, maybe, like a little plastic bag”.

Manolo Blahnik told Pret-a-Reporter, “nowadays I have a weakness for Rihanna”, while the newly engaged DJ Hannah Bronfman (“I was totally shocked” by music manager Brendan Fallis’ proposal) said her icon is Iman and Hailey Baldwin said Gisele. “We all start somewhere”.

But ever the hair chameleon, Katy completely changed her look from head-to-toe after performing at the “Icons” party.

The outspoken star also gave a shout out to the celebs and models exhausted by Fashion Week, yelling to the audience: ‘Ladies, make some noise if you’re in the house. “Fashion Week’s nearly over – you can drink as much as you want”.

It was Katy Perry the crowd was screaming for at the Harper’s Bazaar ICONS event on Wednesday night at the Plaza, but the hotel ballroom was filled with near-icons of its own.

Other guests at the event included TV star/model Kendall Jenner, singer Rita Ora and model/actress Kate Upton. She closed out her 20-minute set with “Firework” which she dedicated to assistants working behind-the-scenes during the fashion week.
