Celine Dion Cancels Tour Because of Husband Rene Angelil's Illness

— -- Céline Dion has canceled her Las Vegas shows and her upcoming tour of Asia to care for her husband, René Angélil, their family, and her health.

Last December, Angélil had surgery to remove a "cancerous tumor," her rep said in a statement, which changed the course of the singer's life.

"I want to devote every ounce of my strength and energy to my husband's healing, and to do so, it's important for me to dedicate this time to him and to our children," the singer told ABC News in a statement. "I also want to apologize to all my fans everywhere, for inconveniencing them, and I thank them so much for their love and support."

For Superstar Celine Dion, Career Is a Family Affair

This past June, Angélil, 72, stepped down as Dion's manager, to focus on his health. However, he has still been involved in business decisions pertaining to his wife's career.

Meanwhile, Dion, 46, has been battling an inflammation in her throat muscles, from which she has not yet recovered. She has not been able to perform since July 29.

"It's been a very difficult and stressful time for the couple as they deal with the day-to-day challenges of fighting [Angélil's] disease while trying to juggle a very active show business schedule, and raise their three young children," said a publicist for the singer. "Céline and family have requested that their privacy be respected at this time."
