Calabasas' soon-to-be-newest resident, Britney Spears, is now an Aunt. Jamie Lynn popped out her baby girl, Maddie Briann, this morning.

Lynn, the millennial face of teen pregnancy, went into a Mississippi hospital at 4:30 a.m. and gave birth a few hours later.

She had announced her pregnancy back in December around the time that Juno was making headlines, sending parents and Nickelodeon lovers into a tailspin and setting off a string of hand-wringing (rightfully so) amongst teen pregnancy experts nationwide.

She and baby are, according to reports, doing well. Britney and her father left Los Angeles and the courtroom drama behind to spend time with the new family member in Kentwood.
