In one recent photo she shared on Instagram, the singer spoke out in support of the Gay and Lesbian Alliance Against Defamation (GLAAD). Adorned in purple and holding her young sons, Dion wrote: “Today we’re going purple in solidarity with @glaad #SpiritDay! I encourage all of you to join us and take a stand against anti-LGBTQ bullying.” She then urged her followers to support LGBTQ youth via GLAAD’s resources. Dion’s beliefs have also informed her parenting itself. “I thought they were going to go for the big superheroes. They were looking at princesses,” she told InStyle of her young sons. “I end up saying to myself, ‘You know what, it’s OK.’ You know why it’s OK? Because they’re talking, they’re finding themselves.” Celine Dion has maintained a four-decade-long career that’s won her countless accolades, including Grammys, Academy Awards, Golden Globes, and more. She’s sold out stadiums, maintained a 16-year residency in Las Vegas, and succeeded by just about every other metric in global entertainment. Yet the singer says that parenting her children is still her greatest accomplishment. “What makes me most proud is to be a mother,” she said to Extra. “I have three magnificent kids, [and] through them, I see my husband and I have the strength today to keep dressing up.” And for more from your favorite celebs’ kids, Julianne Moore’s Daughter Is All Grown Up and Looks Just Like Her.
