Celine Dion has cancelled more shows at Las Vegas' Caesars Palace, citing a virus causing an inflammation of her vocal cords.
The French-Canadian pop star has been ordered to rest her voice for six to eight weeks and is set to resume performances on June 9.
"I tried to sing at my sound check last week, and I had no control of my voice whatsoever," she said in a statement.
"We thought that after a few days' rest I would improve, but it wasn't getting any better."
Officials announced last weekend that Celine was cancelling shows up to March 3.
On Monday, she was diagnosed with a viral illness and weakness in her right vocal cord.
The Las Vegas Strip casino spent $95 million building the Colosseum for Celine in 2003, complete with a humidifier to protect her voice.
After a five-year run, she embarked on a world tour and took time off for her family, giving birth to twin boys in 2010.
