Jamie Lynn Spears did a cover of her sister Britney Spears' song while in Decatur, Ga., on Dec. 5 as part of her country music tour.

The young Spears was in the middle of performing her song Ms. Mississippi, but then transitioned into her sister's 2000 hit Oops!... I Did It Again. Released when Jamie Lynn was just 8, she did the acoustic version of the popular song.

The crowd loved the rendition, cheering and screaming for Jamie Lynn throughout the performance.

Jamie Lynn spoke about her childhood, and being raised with a sister in the spotlight, in an interview in late November. She said her childhood "consisted of being able to travel with my sister." She did not necessary complain about being on the road with her older sibling, saying, "My sister made it really fun. She really made me involved in every part of it."

"Things were different and we were from a small town...back then you just didn't hear those kinds of stories," she said about how fame hit her family. "No one got on the Internet and was famous...you go to a record label, you get signed and that's how things went. So whenever it happened I remember being like 'wait, what? My sister's on the radio? I don't understand."

"I remember my exact words were 'like Mariah Carey? That's how my sister is?' " she added. "That was the first time it clicked for me cuz I had a real comparison as a child."

"Some of the best memories of my life are being on the tour bus with [Britney]...it was like any other childhood, except we were just a traveling circus I guess."
