Jamie Lynn Spears may not want to be known for being Britney's little sister, but she doesn't mind singing a few lyrics to 'Oops! I Did It Again,' the pop star's biggest hit. The younger sister and country newcomer recently performed a mashup of the pop song with her own country song, proving she has talented chops of her own.

At a recent trip to an Atlanta venue, Spears and a three-piece band took the stage for her song 'Miss Mississippi.' She showed the audience she not only has a great voice, but can really do the country thing, to boot.

Spears is hoping this song -- along with her other country songs -- will allow her some spotlight time after a hiatus to raise her young daughter. Although she's living in Nashville these days, the 22-year-old sported a shirt for the set that paid tribute to her home state of Louisiana, which gave her a look similar to one we might see on Miranda Lambert.

When she threw back her hair and began the lyrics to her sister's first-ever hit, the crowd cheered and sang along to the country mashup. Spears even busted out a dance move from the much-watched 'Oops! I Did It Again' video!

To conclude the song, Spears told the crowd, "You gotta throw it back to your sister at some point, right?" And with the audience reaction she got, we'd say they agree.
