Celine Dion's husband, Rene Angelil, passed away in 2016, but he's still a huge part of his children's lives.
On Oct. 23, the singer paid tribute to her twin sons, Nelson and Eddy, on their 10th birthday while referencing Rene, who died after a long battle with throat cancer.
"Nelson and Eddy, you have been bringing so much joy, love and laughter into our lives every single day for the past 10 years," she wrote on Instagram. "You make me, your big brother and your Dad, who is for sure watching over you, so very proud. Happy birthday my beautiful boys! We love you so very much… – Mom, RC and Dad xx…"
Celine's message was accompanied by several current and past images of the pre-teen boys. The images show the boys rapidly becoming young men.
The superstar also shares 19-year-old son René-Charles, 19, with her late husband.
Celine often keeps Rene's spirit alive in Instagram tributes to her kids. On René-Charles' last birthday in January she called him a "true gentleman."
"I'm so proud of the way you're conducting yourself in life," she wrote at the time. "I want you to know that your father's guidance continues to support and protect you… as I do. Keep being the best of yourself… strong, passionate, and wise, as you pursue all of your dreams in life – the sky's the limit!"
She added, "And above all, have a good time!…. Your happiness, is my happiness. I love you so much, my dear son! Mom xx…"
