Ok sorry, but we legit love Justin Timberlake.
Twenty of JT's superfans were invited to help introduce his new album, "The 20/20 Experience," by singing his new songs for a commercial.
Well little did they know, but Mr. "Suit &Tie" himself was standing by ... and his surprise visit garnered some pretty great reactions -- from screams to swears to tears.
We love when celebs do something cool and unexpected for fans, and this video reminds us of the time David Beckham popped up in a photo booth to join unsuspecting British soccer fans.
Aww, JT and the Becks -- not only talented, but good dudes to boot.
Watch Justin surprise his fans in the video above as they sing his new single, "Mirrors" -- with the official video for the song is below.
