Camila Cabello and Shawn Mendes rang in 2016 in the place the Fifth Harmony member calls home: Miami, FL.

Here Are The Things We Hope Happen To Fifth Harmony In 2016!

The pair joined a bunch of other artists for Pitbull's New Year's Revolution so they could perform their duet, "I Know What You Did Last Summer," one last time in 2015.

Plus, we snagged a couple of pictures of the duo on stage, totally in their element!

Cabello was all smiles while performing on stage with her pal in her hometown. She grew up in Miami after making the move from Cuba to Mexico and then finally settling in Florida.

The two singers have definitely given their all on every performance of this duet, so closing out 2015 with it one more time seemed truly perfect.

More so, Cabello gushed her "love" for Miami post-performance on Twitter, noting, "You guys were so amazing."

She has performed in Miami many times now; it's clearly always something so special to perform at home.

"It's so fun/nerve wracking/special performing in my hometown," she beamed.
