Jamie Lynn Spears Talks Teen Pregnancy In Glamour Magazine

Jamie Lynn Spears is back and all grown up, y'all! She may have taken a break from the spotlight after she became a mom, but Britney Spears' little sis is re-emerging as a poised open book in March's Glamour magazine.

Inside the issue, a photo shows a gorgeous, mature Jamie Lynn blowing out birthday candles -- she turns 21 in April! In her interview with Glamour, she confidently reflects on one of the most challenging times in her life: defending her young pregnancy. "I was 16. I'd had one boyfriend. It doesn't make it perfect or all right. But I was judged for something that probably most everyone does. I was young. I was in love..." But, even through criticism from media and fans, Jamie Lynn tried to remain strong: "I did feel responsible for the young girls and the mothers who I probably confused and let down. I apologize for that... But the hateful comments hurt."

The budding country singer also dishes about the future and offers a grown-up perspective on getting back into the music scene: "This is the first time anybody is really meeting me as a grown woman and grown mother making a decision about what to do with my life. Do people have an idea of who they think I am? Yes, and that's fine with me. My music will speak for itself." With that self-assurance (and with big sister Brit as a mentor) we think Jamie Lynn's gonna do just fine.
