Justin Timberlake kicked off night two of the iHeartRadio Festival Saturday, and treated the crowd to a surprise special guest – Shawn Mendes.
“Ladies and gentlemen, I'm a big fan of this young man," Timberlake said. "He's one of the coolest cats I've met, he's very talented, and he's about to bless you -- please welcome Shawn Mendes to the stage.”
The duo then launched into “What Goes Around…Comes Around,” with Shawn tackling the second verse. They then ended the song with a line from Justin’s Chris Stapleton collaboration “Say Something,” with Shawn leaving the stage and Justin an his band continuing on with that song.
In addition to the Shawn appearance, J.T.’s set was jam-packed with hits, including “Sexy Back,” “Cry Me A River,” “Mirrors” and more, wrapping things up with the crowd-pleasing “Can’t Stop The Feeling.” Check out Justin and Shawn’s performance to the right.
