The former Voice colleagues also spent time together on Saturday night, when they performed their duet "Go Ahead and Break My Heart" at the star-studded charity event, Apollo in the Hamptons, at The Creeks in New York. Stefani and Shelton couldn't look happier snuggled up at dinner, where they were joined by Pharrell Williams, Jennifer Lopez, Katie Holmes, Ciara, and Jon Bon Jovi.
