On the night, Caitlyn proudly accepted the honour of Transgender Champion. The former Olympian was joined by daughter Kylie, 18, who made sure she captured lots of special moments on Snapchat before sharing them with fans.
Other guests at the annual bash held at New York's
Carnegie Hall included Selena Gomez, who also stunned in a red dress,
Reese Witherspoon, Amy Schumer and Jennifer Hudson.
Victoria Beckham, who was recognised for her work as a fashion designer and philanthropist, also looked stunning in a striking red dress.
Meanwhile, Caitlyn recently confirmed her name and gender change had been finalised.
"Yesterday was significant, because my name and gender change came through. Holy crap," she revealed."Here we are - honestly never knowing if this day would ever come. In some ways, it's a little sad. Bruce was a good guy, did a lot of good things, raised a tremendous family and wonderful kids. But I just couldn't play that game any longer."
