Irina Shayk, Gigi and Bella Hadid hit the runway at Carine Roitfeld's first CR fashion show

Shut it down.

Carine Roitfeld teamed up with Luisaviaroma to celebrate nine decades of the Florence luxury retailer. Thousands of fashion-insiders and super models flocked to Italy for debut of Roitfeld's CR runway show held at the Piazzale Michelangelo in Firenze.

Lenny Kravitz put on a surprise performance for show-goers, which reportedly crashed Instagram on Thursday night. The 55-year-old rock star and style icon sang “Fly Away,” “American Woman” and “It Ain’t Over ‘Til It’s Over.”

Gigi Hadid opened the show paying tribute to the late Karl Lagerfeld, while sister Bella walked the runway in a look by Off-White, as designer Virgil Abloah sat front row.

Other models who showed out for the event included Joan Smalls and Alessandra Ambrosio who posed with her new boyfriend Nicolo Oddi. Irina Shayk also made an appearance wearing a sexy leather look by Ermanno Scervino featuring latex matching gloves.

This marks one of Shayk's first outings since news broke of her split from boyfriend Bradley Cooper.
