Hours before confirming Posey’s death, Gatterman said the teenager was supposed to be “graduating with honors” next month.
Posey was best known for appearing on TLC’s Toddlers & Tiaras, which originally aired from 2009 to 2013. The high schooler was 5 years old when she appeared on one episode of the reality series, which saw her compete in the California Tropic Arizona pageant, and she became one of the series’ most recognizable faces after her reaction in an interview became a popular gif.

Posey continued to compete in pageants after her brief stint on the show. In January, she announced she was competing in Miss Washington Teen USA in February. “One word. Thankful,” she captioned a post on Instagram.
