Justin Timberlake is postponing his tour by a week because he needs more rehearsal time.
The 32-year-old singer made his musical comeback this year after a six-year break to focus on his acting career.
Justin was originally due to kick off his The 20/20 Experience World Tour in Montreal on October 31 but the first show will now be in New York on November 6.
His Montreal and Boston dates have been rescheduled for the end of the tour, eight months later in July 2014.
The reason for the rescheduling was to give the Suit And Tie singer more time to rehearse. Justin had already performed material from his new album The 20/20 Experience during appearances throughout the year, including a show at London's iTunes festival on September 29.
Justin will play nine dates in the UK in March and April next year, including two shows at London's O2 Arena on April 1 and 2, 2014.
