Shawn Mendes Scares Camila Cabello at the iHeartRadio Festival & It's the Cutest Thing Ever (Video)

Shawn Mendes poses with his good pal Camila Cabello while backstage at the 2015 iHeartRadio Music Festival held at MGM Grand Garden Arena on Saturday (September 19) in Las Vegas.

The singers (and rumored couple) looked like they had a blast hanging out together, that was, until Shawn “fell asleep” on Camila‘s shoulder!

“@shawnmendes and i are in desperate need of caffeine. #iheartradio,” she captioned a cute Instagram photo, which you can see below!

During the red carpet, Shawn came out and scared Camila while she was posing! LOL! Watch the funny video below!
