OK! Exclusive: First Photos of Maddie Aldridge on Wednesday!

(OK! Exclusive Photo)

Maddie Briann Aldridge is here — and only OK! has your first look at her! Check OKmagazine.com Wednesday morning to see the world's first photos of Jamie Lynn Spears' newborn daughter.

Baby Maddie arrived June 19 and is the first child for Jamie Lynn and her fiancé Casey Aldridge. The 17-year-old Zoey 101 star shocked the world in December when she exclusively revealed to OK! that she was expecting. Since then, Britney's little sister returned to her Kentwood, L.A. hometown to prepare for the birth, getting her GED and buying a house in Liberty, Miss. in the process.

In May, Jamie Lynn hosted a girls-only baby shower that reunited her with Britney, who, along with dad Jamie and brother Bryan, flew out for Maddie's birth.

"Right now, I am so focused on the baby," Jamie Lynn has told OK! of becoming a mother. “I just want to be a good mom."
