Watch Demi Lovato And Tove Lo's 'Cool For The Summer' Duet If You're Feeling Chilly

They're basically having the best time ever.

Demi Lovato and Tove Lo are my two new favorite besties.

The two pop stars joined forces on stage to give a very lucky crowd a performance of Demi's hit "Cool For The Summer." The singer was on hand to play her last Jingle Ball concert of 2015 in Tampa, Florida, over the weekend and after performing the first verse of the song, she invited the "Talking Body" singer out to take over.

Tove Lo sang the verse before the two came together on the chorus, which had them blending their voices perfectly as they jumped around on stage and playfully danced with one another with their matching black crop tops.

"There honestly isn't anyone cooler than @tovelo," Demi captioned her Instagram pic of the two. "Thanks lady for coming on stage and performing #CoolForTheSummer with me.. I'm so glad we got to know each other this tour!!"

Now that I'm officially obsessed with these two, can I request they team up to create some new music together?
