Jamie Lynn Spears‘ former All That co-star Adrienne Bailon says newborn Maddie Briann is in good hands.

“She has really grown up — I pray many blessings on her and the new baby,” Bailon (who is in The Cheetah Girls) told Usmagazine at the L.A. premiere of Wall-E Saturday. “I wish her the best. Her mom is the sweetest woman. A baby is always a joy!”

Maddie — who was born Thursday — weighed 7 lbs., 11 ounces. She’s the first child for the former Zoey 101 star, 17, and fiancé Casey Aldridge, 19, a pipe layer.

On Saturday, Spears left the Mississippi Southwest Regional Medical Center in McComb, Mississippi, two days after giving birth.

Bailon, 24, said she is no rush for mommyhood.

“100 percent, I will be married when I have my first child,” she told Us. “I know that is a pretty big statement, but my mom would murder me. I come from a super religious family.”
