The two singers later hit the stage to perform their new duet, “I Know What You Did Last Summer”.
“Shes stoked because i didn’t know the chords and she did hahaha,” Shawn shared on Instagram earlier with a cute vid of him and Camila jamming to “Your Body is a Wonderland” by John Mayer.
FYI: Hailee wore a Yeezy top, John Paul Ataker pants and Rona Pfeiffer on the Jingle Ball red carpet. For her performance, she wore a custom look with Guiseppe Zanotti sneakers. At the Flaunt party, she wore a Rosie Assoulin jumpsuit, Loree Rodkin jewelry and Judith Leiber clutch.
