THE EVENT The third annual Fashion Rocks concert, curated by Elton John and held at Radio City Music Hall. Proceeds from the concert will benefit John's AIDS foundation.

THE PERFORMERS Christina Aguilera, Beyoncé, Bon Jovi, Black Eyed Peas, Jay-Z, Nelly Furtado, Rihanna, Tim McGraw, Faith Hill and many others.

THE HIGHLIGHTS Elton John performed duets with several members of his handpicked musical lineup. Christina Aguilera was stunning in a beaded flapper dress as she sang to his accompaniment. The Pussycat Dolls took turns dancing seductively against John's back as they shared his piano bench. But the hottest duet of the night was Beyoncé—decked out in a belly-baring outfit—sharing the stage with Jay-Z.
