5H's Ally Brooke and Camila Cabelloas well as Mahone posted pictures to their Instagram accounts from the party, which E! News reports took place in Los Angeles on Friday night.

Judging by the snapshots, Mahone and Cabello seemed to have a pretty great time despite confirming their break-up back in late November.

"I've never had a better tasting sea salt caramel cupcake," Steinfeld wrote about the party. "I've never felt so much pain in my feet from dancing. I've never been more excited for a song to play then when Uptown Funk did. And I've also never had balloons spell out my name before."
