Jamie Lynn Spears Gives Birth to a Baby Girl

Pop open a bag'a' them spicy Cheetohs! There's celebratin' to be done!

As we reported a few days ago, Britney Spears was spotted in LAX making her way to Louisiana to be present for when younger sister Jamie Lynn Spears gave birth. And, according to CNN, the time has come!

CNN reports that 17-year-old Jamie Lynn gave birth to a baby girl in a south Mississippi hospital, citing an unnamed source who is close to the Spears family. The family has yet to officially announce the birth. Unless we have another case of the Brad 'n' Angie's on hand (which we doubt), it's probably safe to say:

Congratulations to Jamie Lynn and her fiance Casey Aldridge! Looks like little Sean and Jayden have a new baby cousin to pick on : )
