Celine Dion and her son at the opening ceremony of the film

Dion described keeping it from ‘the people who got her to where she was’ as a huge ‘burden,’ explaining that it felt like she had to act like a ‘hero’ while secretly feeling like her ‘body was leaving her.’ In a teaser for the upcoming chat, which will air in full on Tuesday at 10pm ET on NBC, Celine explained that when she first started to realize something was wrong, she didn’t ‘take the time’ to figure out what was going on. She recalled struggling while her husband, René Angélil, battled his own slew of health woes; he passed away from throat cancer in 2016.
