"On June 19, 2008, Spears gave birth to her first child with Aldridge, a daughter, Maddie Briann Aldridge, who weighed 7 lbs 11 ounces, at 9:33 A.M. CST at Southwest Mississippi Regional Medical Center in McComb, Mississippi, which is the same hospital where Spears was born at on April 4, 1991. OK! magazine reportedly paid $1 million for the first baby pictures for their July 10, 2008 issue."
If she's 18 now, and she had the baby last year when she was 17 for a few months, she turned pregnant at 16. WOW... I always thought she got pregnant at 17... But hey i guess it's better than under age sex.
