Justin Timberlake has postponed two upcoming appearances in America in order to rest his voice.
The singer is understood to be suffering from a vocal strain which has been triggered by a heavy performance schedule.
The two shows in San Jose and Sacramento, California will now take place on 23rd and 25th September.
Timberlake is due to conclude his FutureSex/LoveShow world tour later this month, concluding a year which saw him pick up four awards - including best male - at the recent MTV Video Music Awards.
