Jamie Lynn Spears will share her life with the world this weekend. Jamie Lynn Spears: When the Lights Go Out will air on June 26 on TLC, and the former teen star and country singer will share her life story about her teenage pregnancy, leaving the spotlight to raise her daughter and her debut at the Grand Ole Opry.

In a new clip previewing the hour-long special on People, Spears reveals how her very personal song "When the Lights Go Out" came to be.

"Whenever I wrote 'When the Lights Go Out,' it was coming from a place ... it was the first night, of course, that Maddie was away from me," Spears says, breaking down in tears discussing the song's inspiration. "She was with her dad for the first time, and I was by myself. In that moment, I called Daddy – I was just by myself, and I was just like: I want to be able to let people into that side of me because that's the story. That's why I'm doing it. As you can tell, the music moves me, of course, but it comes from moments like that."

In the clip, Spears and her father, Jamie Spears, and business manager, Lou Taylor, are planning her Grand Ole Opry debut when her father suggests she perform the song on the famed stage.

"It reminds me of exactly why I'm still driven to do this ... for this baby girl."
