And at a stop in Decatur, Ga., on Dec. 5, Spears the Younger gave the audience a little Throwback Thursday action.
In the middle of performing her song "Ms. Mississippi," Spears seamlessly transitioned into her sister's 2000 hit "Oops!… I Did It Again." Released when Jamie Lynn was just 8, the original was a landmark for Max Martin's synth-driven production, but it turns out the song works just as well as an acoustic track.
As anyone who's screamed a Britney song at the top of their lungs on a Friday night can attest, nailing the vocal melodies is harder than it looks. Props to Jamie Lynn for attempting it without the aid of one of her sister's famous backing tracks.
Watch the video above, and then read what Britney had to say about Jamie Lynn's engagement.
