The 25-year-old from Basking Ridge is no stranger to performing as a member of her family's musical group called the Sharpe Family Singers.
They bill themselves as a modern-day Partridge Family and have gained more than 5.5M followers on TikTok.
Samantha says she's been singing since before turning a year old and she's been watching Idol since the first season when Kelly Clarkson won.

Having her family on stage during her performance also meant the world, she said.
"I was hoping I could get to experience this whole thing with my family and that made it so much better for me. I do everything with them when it comes to singing and having them there was like my rock the whole time," she said.
A bit of trivia... Samantha's parents met as romantic leads, Marcus and Cosette, in the original Broadway production of Les Misérables.
According to the Sharpe family's website, the full recording of the song that Samantha performs on 'American Idol' will be released after the show.
