Celine Dion, who returned to Las Vegas’ Caesars Palace a year ago for a three-year engagement, has been ordered by her doctor to rest her voice for six to eight weeks due to a virus that has caused an inflammation of her vocal cords. Officials had already cancelled shows through to March 3rd, but following the diagnosis from her doctor on Monday, more shows were cancelled. The Canadian chanteuse will resume performances June 9. Celine said in a statement: “I tried to sing at my sound check last week, and I had no control of my voice whatsoever. We thought that after a few days’ rest I would improve, but it wasn’t getting any better.” Celine returned to the Colosseum — which was built for her in 2003 at Caesars Palace — after performing a five-year run there. She then completed a world tour and gave birth to twin boys in 2010 before returning to Las Vegas, where tickets for the show sell for up to $250 each.
