Hard to believe it, but little Jamie Lynn Spears turns 21 today!
Britney's younger sister has also grown up in of the public eye thanks to her famous family and starring roles on "All That" and "Zoey 101" when she was only 9 years old.
She was further trust into tabloids at the age of 16 when she announced she and then-boyfriend Casey Aldridge were expecting a child together.
Since then, Jamie Lynn has traded fame for motherhood, raising daughter Maddie in Kentwood -- far away from Hollywood.
She's recently started performing some new, country-sounding songs at local bars -- so her return to the spotlight could be coming!
Check out Jamie Lynn's transformation over the years in the gallery above.
And Happy Birthday!
