It looks like the Las Vegas crowd is going to have to wait a little longer to get a taste of Janet Jackson's Unbreakable World Tour.
According to Billboard, the "No Sleeep" singer has cancelled her shows at Las Vegas' Planet Hollywood Resort & Casino next week, saying that she needs to rest her vocal chords.
But have no fear!
Jackson promised to reschedule her concerts in the city at a different venue next May. Ticket holders will receive a full refund and can snag their seats for next year's show beginning Oct. 16.
