The likes of 5 Seconds of Summer, Nick Jonas, Zedd, Demi Lovato and Tove Lo performed at the seventh annual 93.3-FLZ Jingle Ball on Saturday night. One of the highlights was during Demi Lovato’s set when she brought out Tove Lo for a duet of “Cool for the Summer.”

The audience in Tampa, FL. had no idea Tove Lo was going to come out, and she made sure to make the most of it. She performed the second verse of “Cool for the Summer.” The pair looked great together, playing off each other as they worked the stage. The final minutes of the song were accompanied by confetti falling from the arena.

Afterwards, Tove Lo and Lovato thanked each other on Instagram for a great night.

 

Thank you for bringing me on stage tonight babe @ddlovato 💃🏻👊 #coolforthesummer
