Jamie Lynn Spears had a baby with that body?

This 21-year-old mommy enjoyed a day by the pool with her daughter Maddie this past weekend. She tweeted a pic of her and her little girl enjoying the beautiful weekend with a caption hashtagging:

While Jamie Lynn was pregnant she gained an estimated 20 pounds. Post baby she was determined to ditch the baby weight.

But Jamie Lynn said she did not want to hire an expensive personal trainer:

You don’t have to pay somebody a bunch of money to make you skinny again. If you want to be skinny, you have to do it yourself. And I love to swim, so I know I’ll be doing a lot of that.

Was what she told the magazines while pregnant with Maddie three and a half years ago. Clearly Jamie Lynn Spears has held true to her word, showing Maddie how much fun a day at the pool could be.
