Sporting some serious bling, it seems the younger Spears is happy and ready to start a new life as Jamie Lynn Watson. She was once engaged to Casey Aldridge, the father of her daughter Maddie—which she had when she was just 17. Aldridge and Jamie Lynn split in 2010.

Spears spoke to Glamour last year about her unplanned teenage pregnancy and then-boyfriend Casey Aldridge.

"I was 16," Spears, now almost 21, told Glamour, "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. I was like every other teenager, except I had this last name."

She also explained her controversial interview with Ok! magazine.

"I wasn't trying to glamorize teen pregnancy," the former "Zoey 101" star said. "I hated when [the tabloids] said that. Everybody is dealt a hand of cards. It was my choice to play them the way I played them." 

Also adding: "It's sad because my and Casey's love had to turn into an adult relationship so quickly," she said. "There's a slim chance of two young people making it through high school and all that drama, but making it as parents? We tried. We really wanted to do it right. We loved each other. I will love him as Maddie's father until the day I die." 

Spears is currently working on her debut country album.
