Jamie Lynn Spears!Happy Birthday

Jamie Lynn Spears!Happy Birthday amie Lynn Spears, America's favorite unwed teen baby mama (sorry, Bristol Palin), is just a year away from no longer being a teen. Maddie Briann's mom is 19 today!

The little sis of Britney Spears, who desperately needs a role model, has actually done the right thing and laid low, focusing on being a parent since she gave birth.

Maddie Briann was born in June 2008. She and baby daddy Casey Aldridge since split, but Jamie Lynn is going strong and setting a good example for teenagers.

As in, do not follow this example!
