Kailia Posey, a former star on TLC's "Toddlers & Tiaras," has died, her mother announced on social media. She was 16.

“I don’t have words or any thoughts. A beautiful baby girl is gone. Please give us privacy as we mourn the loss of Kailia. My baby forever,” Marcy Posey Gatterman said in a Facebook post on Monday. 

Her cause of death was unclear. Gatterman did not immediately respond to a request for comment Tuesday.

Posey was best known for being featured in one episode of "Toddlers & Tiaras," a TLC reality TV series that focused on the families of children who competed in beauty pageant competitions. 

A photo of her reaction in an interview during the episode led her to become one of the most recognizable faces in the series.

Her mother posted several photos of Posey on Facebook, including one of her daughter with a halo around her head.

Just last Saturday, the proud mother posted photos of her daughter and friends smiling together on their way to prom.

“In terms of his on-air appearances, we’re just going to have to see how it plays out going forward.”
