The engaged 22-year-old did recently open up about her "second baby" in an interview with E! News, but that doesn't mean little Maddie won't be getting a brother or sister anytime soon.
So, what was she talking about?
Jamie Lynn has been working on her very own album!
We will get a little taste of Jamie Lynn's singing on big sister Britney Spears' new track "Chillin' With You," which will be appearing on Britney's upcoming 'Britney Jean' album, but it sounds like Jamie Lynn will be going country when it comes to her own record.
During a Twitter chat with fans, she did reveal that the album is straight from the heart, which can also be said of this rare interview, where she explains the not-so-glamorous way she found out she was pregnant and spills about her love for singing.
Check out the clip below to see what she had to say.
