JAMIE LYNN SPEARS SOCCER MOM DREAMS

Fomer teen prego queen JAMIE LYNN SPEARS, now 21, tells ALL in a white knuckle interview about boys, a lack of birth control and big sis Britney!

After shocking the pre Bristol Palin world when she announced she was pregnant at 16, Jamie quit show business to disappear into the Louisiana bayous.

Now a 21-year-old parent to daughter Maddie, Jamie Lynn told Glamour mag how she worries she is not a good parent.

"I (NOW)  believe in safety and birth control as prevention," Jamie Lynn said. "But like many young girls...I was really scared to go to the doctor. And I was on a Nickelodeon show, and it (was) embarrassing to ask someone to put me on birth control. I didn't want to ask my doctor, because she had a little girl."

Despite their best efforts to make it work, former fiancée Casey Aldridge and Jamie Lynn busted up amid reports of cheating and ennui.

"These days, the only thing I'm afraid of is not being a good mom," she admits. "As long as Maddie is healthy and she loves me, the rest doesn't matter."

Single and living in Nashville, Jamie Lynn is following in her sister Britney's footsteps -- building a music career and concentrating on being a mom.

“I just want to be a soccer mom. I want to cook dinner every night. I want the kids to come home and be dirty and make the house messy.

 “At the same time, I have to be patient and wait for the right time and the right guy. I would have never known that until I went through what I went through.

"I'm just patiently waiting for Prince Charming."

He's a fairy tale, Jamie.
