Fifth Harmony's Camila Cabello and Shawn Mendes teamed up for one of the coolest collaborations to end 2015!

Camila Cabello Knows What Makes A Sleepover Perfect!

Their duet "I Know What You Did Last Summer" has become an anthem and the talented pair have gotten the chance to perform it live on multiple occasions.

Some of those occasions would be on the Jingle Ball tour that took place throughout this month. They shared the stage seven times for this epic duet during the Jingle Ball run.

Radio station 93.3 FLZ's Jingle Ball was the last performance for the 18-year-old girl group member and 17-year-old Canadian musician, taking place on Saturday, Dec. 19 with Y100's Jingle Ball in Miami coming just the night before. The pair also hit the stage in Atlanta for POWER 96.1's Jingle Ball on Dec. 17 and the day before they were in Chicago for 103.5 KISS FM's Jingle Ball. The biggest Jingle Ball just might have been the one for Z100, which took place at Madison Square Garden on Dec. 11. The pair also amazed a Los Angeles' crowd at 102.7 KIIS FM's Jingle Ball on Dec. 4. On Dec. 1 they played in Dallas at 106.1 KISS FM's Jingle Ball, which kicked off their run together.

In honor of their seven performances, Cabello took to Instagram to reflect sharing seven images, one from each of the performances, along with a sweet message for Mendes and his team.

She initially referred to him as "Canadian Fury" since that's his nickname, while gushing over the seven images she selected, which range from their end of the performance hugs to them getting really into the tune.

"LMAO these pictures make me laugh because we would literally just crack up at the end of this song every night," she revealed, adding, "Thank you to this lovely human @shawnmendes for inviting me to perform during his set on these Jingle Balls."

"I had such a blast watching you kill it every night and then coming on to sing IKWYDLS," she gushed, while thanking his team too for allowing this all to happen.

Cabello and Mendes certainly have ended 2015 on a high note, right?
