Las Vegas - Singer Celine Dion has cancelled more shows at Las Vegas' Caesars Palace, citing a virus causing an inflammation of her vocal cords.
An official with show producer AEG Live, Christi Nelson, says a doctor has advised the French-Canadian pop superstar to rest her voice for six to eight weeks.
Officials announced last weekend that Dion was cancelling shows through March 3. Her new return date is June 9.
The singer of romantic odes including My Heart Will Go On and It's All Coming Back to Me Now returned to Caesars Palace a year ago for a three-year engagement.
The casino spent $95m building the Colosseum for Dion in 2003, complete with a humidifier to protect her voice.
