Britney isn't the only Spears sister with her hands full these days: The X Factor judge's younger sib, Jamie Lynn, is keeping busy, too.
Over the weekend, Jamie Lynn, 21, tweeted several adorable pics of herself and 3-year-old daughter Maddie having fun by the pool.
"#littlegirls #littlemoments" the former Zoey 101 star wrote, linking to an Instagram shot of herself and Maddie enjoying the sun in pink bikinis.
And while Jamie Lynn was only 17 when she and then-boyfriend Casey Aldridge welcomed their little girl, she has no regrets about being a teen mom.
"Casey was my first love. Since the day I saw him, I just wanted to marry him and be with him forever and ever," she told Glamour magazine earlier this year. "I believe in safety and birth control as prevention. But like many young girls...I was really scared to go to the doctor."
"I did feel responsible for the young girls and the mothers who I probably confused and let down. I apologize for that. But I wasn't trying to glamorize teen pregnancy," she added. "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. But the hateful comments hurt."
