It's no secret that Shawn Mendes and Camila Cabello are close friends, but when they do adorable things like this online, we melt.
After Camila performed her hit song "Havana" on Late Night With Jimmy Fallon, Shawn took to Twitter to let the world know that he was OBSESSED with her, just like us.
"Are you seeing this sh*t!!! @Camila_Cabello is literally the coolest person on planet earth!" he wrote.
OMG all the heart-eye emojis.
The best part was that Camila responded to the tweet, writing, "i just texted u saying this but u are the kindest most supportive friend ever!!! love u 4ever Canada."
We will never recover from this.
