Justin Timberlake has postponed the start of his forthcoming world tour.

Shows in Montreal and Boston have had to be rearranged for summer 2014 due to extended rehearsals.

Originally scheduled to visit Montreal’s Bell Centre and on October 31 and November 1, Timberlake’s ‘20/20 Experience’ shows will now take place on July 25 and 26 2014.

Fans with tickets for the ‘Sexy Back’ star’s November 4 show at Boston’s TD Garden will now have to wait until July 14 2014.

The change in dates now means that the opening concert of Timberlake’s tour will take place in New York at Brooklyn's Barclays Centre on November 6.

‘The 20/20 Experience’ tour will visit the UK in March and April 2014.

Although he co-headlined the ‘Legends of Summer Stadium Tour’ with Jay Z earlier this year, Justin Timberlake’s last solo live outing was 2007’s ‘FutureSex/LoveShow’.
