The short black-and-white teaser sees Bieber sitting between Skrillex and Blood Diamonds, who collaborated with him on the track, reported Aceshowbiz.
The 21-year-old star, donned a white T-shirt teamed with black hoodie and hat, sings some lines over the acoustic guitar played by Skrillex.
"Who's ready for sorry I know I Am," Bieber captioned the clip. He added some plane emojis, tagged his collaborators and added the hashtag "#3days."
"Sorry" will be the second song to come preceding Bieber's new album "Purpose" that's due out on November 13. Previously on Monday, the singer previewed the track in a Michelle Obama-starring video made and shared on Twitter by Vine and TV star King Bach.
