Camila Cabello and Shawn Mendes vow to strip naked if they win a Grammy

At the 2017 Grammys, Twenty One Pilots accepted their award in the underwear, after revealing that one time, many years ago, they were watching the Grammys together in their underwear. They promised each other, "If we ever go to the Grammys. If we ever win a Grammy, we should receive it just like this."

Cute!

However, Camila might just be kidding. 

"Just kidding. It’s not [a promise]. I gotta work out before I do that," she said, laughing.

Here's hoping!
