LAS VEGAS (AP) - Superstar singer Celine Dion has been forced for cancel several concerts in Las Vegas because of a virus.

Caesars Palace officials say her doctor advised her to rest for a week to recover from the virus, which caused an inflammation of her vocal chords.

Shows scheduled for Friday, Sunday, Tuesday and Wednesday were
canceled at the resort's Colosseum. Her next scheduled concert there is March 3.

Dion, in a statement, said she doesn't "like to let people down," and she feels "terrible" about not being able to perform at the shows. She said she hopes "everyone understands how sorry" she feels.

Refunds will be given to people who bought tickets.

Caesars spent $95 million to build the Colosseum for Dion in 2003, complete with a humidifier to protect her voice
