As we know, these two make beautiful music together and Demi joined Nick on the tune for his new album. But to hear it live? Yeah, this one is worth some repeat viewings.
Nick tweeted after: "Amazing show last night for @1027KIISFM jingle ball! Thanks @ddlovato for coming and singing Avalanche with me!"
Earlier this week, Demi and Nick shared a moment hanging by a plane, which Demi posted on Instagram, writing: "@nickjonas We look really cool. Way cooler than we actually are. They still get jealousssss"
God we love these two together.
