Janet Jackson is canceling her Oct. 9 and Oct. 10 shows at Planet Hollywood Resort & Casino to rest her vocal cords, and the Las Vegas stop on her "Unbreakable" tour will move to a new 20,000-seat arena in May.
Live Nation Entertainment said Thursday that ticketholders will be refunded and have the first chance to buy tickets for the May 14 performance. Tickets go on sale Oct. 16.
The move is a loss for Caesars Entertainment Corp., which owns the venue at Planet Hollywood that features regular performances by Britney Spears and soon Jennifer Lopez.
MGM Resorts International is working with concert presenter AEG to open the new arena behind MGM's New York-New York and Monte Carlo resorts in April.
Jackson's comeback album, "Unbreakable," is being released Friday. It features the single "No Sleeep" with J.Cole, which was produced by Jackson's longtime producers Jimmy Jam and Terry Lewis. The set marks Jackson's first studio effort since 2008.
