New York Fashion week brought a night of hot models, amazing performances and bootyliciousness to the Fashion Rocks event at Barclay’s Center on Tuesday.

The show was hosted by Ryan Seacrest, who looked absolutely dapper in a suit and blue bow tie.

The evening began with the very anti-climatic entrance of Usher, introduced by a pre-taped motorcycle ride through NYC. He proceeded to perform “She Came to Give It to You” with some help from Jourdan Dunn who looked stunning!

The rest of the performances failed to disappoint. Here are some of the night’s highlights:

1. Pitbull’s Gatsby-esque performance of “Fireball.” It’s always a party with Pitbull.
