In a post on Instagram, the American singer and actor apologized to fans, announcing that six of his upcoming concerts in US venues will be postponed until February.
Earlier this month, the 43-year-old postponed his Forget Tomorrow world tour date at the last minute due to an unspecified injury.
Giving a health update in his latest Instagram post, the NSYNC singer-turned-solo star wrote: ‘Hey guys – I haven’t been feeling well for the last few gigs and it turns out I have bronchitis and laryngitis.
“I am very sorry to say that I have to reschedule the next few shows from 10/23 to 11/2. New dates listed above.
“Thank you for your understanding – I’ll make it up to you – JT.”
Bronchitis is inflammation of the airways in the lungs, usually caused by an infection, while laryngitis is when your voice box or vocal cords in your throat become irritated or swollen, according to the NHS website.
Timberlake was scheduled to perform in Columbus, Ohio on Wednesday night before hitting the stage in Detroit, Michigan and Chicago, Illinois on Friday and Sunday.
His shows in Grand Rapids, Michigan, Milwaukee, Wisconsin and St. Paul, Minnesota are also being rescheduled.
It comes a month after Timberlake pleaded guilty to drunken driving, resolving a criminal case stemming from his June arrest in the Hamptons in New York state on a drunken driving charge.
The singer and actor was fined $500 (£380) with a surcharge of $260 (£198), ordered to do 25 hours of community service at a non-profit organization of his choice and ordered to make a public safety announcement.
