Jamie Lynn Spears said she was completely shocked when she found out she was pregnant at the age of 16. She had a hit show on Nickelodeon called "Zoey 101" at the time and dropped out of the limelight shortly after announcing the baby news in December 2007.

Britney Spears' little sister has kept a relatively low profile raising her daughter, Maddie, in her home state of Louisiana. Now the 22-year-old is back in the spotlight thanks to her big sis. Jamie opened up to E! News about her teen pregnancy and what she is calling "her second baby."

 "I was riding around in my mom's little convertible and I had not been feeling well. I thought it was just stress with work and all kinds of different things. My friend was like, 'Why don't you just take a test?' I was like, 'Okay, I will.' We were filling up with gas, so I went in the gas station and took the test and it was positive," she recalled. "So that is the glamorous way that I found out I was going to have my little nugget!"

Jamie told E! that she had a hard time accepting the news because she was so young but now that her daughter is older she is ready to step back into the spotlight. She said that she is planning on releasing a debut CD but first was teaming up with Britney for a song. The track, called "Chillin' With You' will be featured on Britney's eight studio album "Britney Jean."

"I don't think you just wake up one morning and decide you're going to sing. It's something I've always done," she said. "But as a young child, like I said, all that was offered to me. You don't know how to say, like 'Oh, this is what I want for the rest of my life.' You can't make those kinds of decisions at 10 years old."

The former teen star, who is engaged to her boyfriend of two years Jamie Watson, said she is nervous for the world to get a taste of her "second baby" but now that her music career is finally starting to take off she is completely excited.
