Justin Timberlake and Shawn Mendes iHeartRadio Performance

Justin Timberlake and Shawn Mendes Performed a Sexy Duet, and BRB While We Try to Find Our Chill

Two of our favourite heartthrobs just shared the stage, and we've officially lost our chill! During the iHeartRadio Music Festival on Sept. 22, Justin Timberlake surprised the crowd by bringing out Shawn Mendes for a special performance of "What Goes Around . . . Comes Around," and it was just as epic as it sounds. The two showed off their swoon-worthy vocals as they crooned the lyrics to the stripped down version of the song.

Before bringing Shawn on stage, Justin couldn't help but gush about the 20-year-old saying he was "one of the coolest cats I've met." And it seems like Shawn was just as star-struck. After their duet, the singer thanked Justin on Instagram writing, "Thank you @justintimberlake for being such an incredible guy." Can these two do more music together ASAP?
