Jamie Lynn Spears made her musical debut in Nashville last week, and now two videos of the performance have surfaced online.

The 20-year-old showed off her vocal chops with two original songs for the intimate crowd, accompanied by a small acoustic backing band. Spears wavered in pitch at times, but her tunes reflected a pop sensibility that could take her straight to country music stardom.

While big sister Britney Spears was not in the audience, we're sure she was as proud of her sibling as her parents were. According to PEOPLE, mother Lynne Spears gushed, “I am so emotional tonight,” and father Jamie Spears added, “We are so proud of her.”

"Just wanna thank all my amazing friends and family for coming out tonight!!!" Jamie Lynn wrote on Twitter after the performance.

The younger Spears sister spent several years in the entertainment industry, playing the title role in Nickelodeon's hit show 'Zoey 101.' She sang the show's theme song, ‘Follow Me,’ and also contributed to the ‘Unstable Fables: Goldilocks and the 3 Bears’ soundtrack, as well as Triple Image's tune ‘Hey Now (Girls Just Wanna Have Fun).'
