Contrary to recent reports alluding to Jamie Lynn Spears’ ‘nightmare pregnancy,’ friends insist the Zooey 101 star is taking it all in her stride.

In fact – with just three months to go before she drops – Britney's 16-year-old sister is said to be impressing her family with just how well she is dealing with impending motherhood.

"She has such a level head on her. She is handling this situation with a maturity that is surprising even her own family," a friend tells OK!.

"She's behaving like a pretty normal teen," the friend adds.

"She's not even worried about how much weight she puts on or doing any special exercises. At her age, her body will bounce right back and she knows it."
