You watch Sabrina Carpenter every week on Girl Meets World and listen to all her covers on YouTube. Think you know everything about the star? If you're a Sabrina stan, this may not be news. But if you only casually follow her Instagram feed, you might not realize this one fact about her — the Disney Channel star has a half-sister named Cayla Carpenter.

The 24-year-old freelance makeup artist and hairstylist often appears on her sisters' Instagram accounts, and their dad, David Carpenter, frequently posts adorable pics of all his daughters. They're the cutest family ever!

With Sarah Carpenter guest-starring on GMW and harmonizing with Sabrina onstage, Shannon Carpenter has joked about being "the unknown sister" of the Carpenter clan, but the Cayla is totally under-appreciated. It's time she gets the recognition that she deserves!
