Celine Dion has postponed her Las Vegas residency and her Asia tour to support her husband as he battles cancer.

“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 42-year-old singer told People. “I also want to apologize to all my fans everywhere, for inconveniencing them, and I thank them so much for their love and support.”

Last December, Dion’s husband, René Angélil, 72, had a tumor removed from his throat. He was first diagnosed with throat cancer in 1999.

In March, she said in a statement, “I don’t want René to stress out with work-related issues. I want him to focus on getting back to 100%.”

The couple have three children together: René-Charles, 13, and twins Eddy and Nelson, 3.
