Jamie Lynn is rolling out her country career and what a better way to do that than with a TV doc? The show is titled "When the Lights Go Out" and it documented Jamie Lynn's journey from the recording studio all the way to the stage. Of course the show wouldnt be complete without an appearance from her big sis Britney who first joined her in the recording studio, no not for a remake of Chillin wit Chu, but to listen to Jamie Lynn's new single. Then she made a surprise appearance at Jamie's show where she introduced her to the crowd. Check out the entire Spears family in the vids.
