Sunday was a big night for Rene-Charles Angelil.
After Celine Dion's 15-year-old son surprised his mom
by presenting her with the Icon Award at the 2016 Billboard Music Awards, he snapped a pic with Rihanna backstage
that he shared to Instagram, writing, "What a night!"
It was an emotional night for Rene-Charles and Celine, who made their first televised appearance after legendary talent manager Rene Angelil died in January, two days shy of his 74th birthday. Rene was Rene-Charles' father, and Celine's husband of 21 years.
After a breathtaking performance of "The Show Must Go On," Celine wept when her son joined her on stage.
"I'm sorry for crying," Celine said to her son, holding his hand as tears rolled down her face. "I want to be so strong for my family and my kids and I didn't expect this. I didn't want to cry in front of you, you make me so happy."
"Rene, this one's for you," she added. "The show must go on!"
Backstage, the legendary singer shared with ET's Cameron Mathison what was going through her head during the emotionally charged moment.
"You have to be strong, but I think it's important as well to not hold everything," she said. "I tried to hold it in front of my 5-year-old twins, but my 15-and-a-half year old beautiful son is old enough to understand.
"Even though I did not want to cry, he understands it's okay because it is therapeutic and you can't take so much pressure," she continued. "You can take so much strength and weight on your shoulders, but sometimes you can't control everything."
