"My sweet boys, you are turning 8 today and you make me proud every day," Dion wrote, alongside a photo of herself, he twins, and her eldest son, René-Charles. "I love you with all my heart and wish you a very happy birthday!"
In the photo, Dion is smiling and playing around with her sons, who are each holding up peace signs, as René-Charles smiles on in the background.
Dion -- who welcomed all three of her sons with late husband René Angélil -- doesn't share many photos of her charming sons, but when she does it's always alongside a kind and loving tribute.
Back in January, to celebrate René-Charles' 17th birthday, the "Power of Love" songstress shared a cute pic of her and her son, captioned with a heartfelt message.
"I love you more and more each day, and I'm so proud of the young man that you've become," Dion marveled in the touching B-day post.
