The former Nickelodeon star is currently pursuing a career in country music, and sang at a showcase in Nashville, Tennessee on Thursday (June 14).
During her performance, Jamie Lynn sang a new song called 'I Look Up to You'.
The heartfelt country ballad's lyrics included: "Scared little girl living in a big old world. You've outgrown your room. It all happened way too soon. They took away your innocence, we forgot our strong defence."
"You can imagine who I wrote it about," she told the audience.
Britney Spears is currently filming the new series of The X Factor USA with judges Simon Cowell, LA Reid and Demi Lovato.
