The "My Heart Will Go On" hitmaker has been juggling her Las Vegas concert residency with nursing her manager beau back to full health since Dec. 23, when the 72-year-old had the tumor successfully removed.
In a statement released to People, Dion says, "I don't want Rene to stress out with work-related issues. I want him to focus on getting back to 100 percent. I've been doing my shows at the Colosseum [in Las Vegas] and everything's under control.
"At home we've been spending a lot of quality time with the family. We feel very fortunate that we've been able to get the best care possible and we thank God every day for helping us get through this ordeal."
Dion, 45, and Angelil are parents to three children, 13-year-old son Rene-Charles and four-year-old twin boys Eddy and Nelson.
