Kailia Posey, a 16-year-old pageant queen who appeared on TLC's "Toddlers & Tiaras" when she was five years old, has died, her mother announced on Facebook.
Posey appeared on "Toddlers & Tiaras," which gave a behind-the-scenes look at the world of children's pageants, at least twice.
In a 2016 episode of the show, Kailia's mom said she started doing pageants when she was three years old.
During a 2012 episode of the show, Kailia, then 5, made a grinning face that went viral as a meme, making her face recognizable even outside the "Toddlers & Tiaras" world.
Posey recently competed in the Miss Teen Washington pageant.
On Saturday, her stepfather, Steven Gatterman, posted that it was her prom night.
On April 19, he posted a message for her 16th birthday, writing: "Happy Sweet 16, Kailia! You are beautiful inside and out. Your light shines bright everywhere you go. Have the best day!".
