Claire Ryann Crosby became a singing sensation at the age of 3 when a video of her performing a Disney song from the Little Mermaid went viral. Her covers can be found on the YouTube channel The Crosbys. She made her first television appearance on Little Big Shots (2016) in 2017 at the age of 4. She also appeared on The Voice (2011) with her father. In 2018 she made her Acting Debut as the role of Rose in the feature film The Little Mermaid (2018). In 2019 she voiced the character of Unitee in the film Spies in Disguise (2019). She also played Orphan Girl in the feature film Anastasia: Once Upon a Time (2020). She is the oldest daughter of Singer Dave Crosby. She has a younger brother named Carson & a younger sister named June.

Her father, Dave Crosby—a musician and record producer with a YouTube channel—is the creative force behind their music videos. In an interview with parents.com, he detailed the story behind Claire’s singing:Claire learned to talk at a super young age and we noticed really early on that she could carry a pitch. I remember some time after her first birthday, she was slamming her hands on our little keyboard in the living room. She started hitting the same note over and over, and then she began to sing the exact same note. I was sure at that moment that she was going to be able to sing.
