Jamie Lynn Spears has given birth, a source tells Joynews.

Daughter Maddie was born Thursday at Mississippi Southwest Regional Medical Center in McComb, Mississippi.

Maddie weighed 7 lbs., 11 ounces.

This is the first child for 17-year-old actress and her 19-year-old fiance Casey Aldridge, a pipe layer.

On Wednesday, sister Britney and dad Jamie flew from L.A. to their hometown of Kentwood, Louisiana as Jamie Lynn prepared to give birth.

The Zoey 101 star – who announced she was expecting at 16-years-old with Aldridge’s baby in December (they sold the story for $1 million) – spent her pregnancy in Kentwood and McComb.

“She’s now really excited, so I’m proud of her,” pal Miley Cyrus has told Joynews.

Before her pregnancy, Jamie Lynn told Us of having kids, “Whatever happens, happens, I guess. You can’t really say what is going to happen.”

In May, Britney and mom Lynne attended her baby shower at the family’s Serenity mansion in Kentwood.

Jamie Lynn and Aldridge got engaged in March and have delayed their wedding until after the birth of their child. At the time, Jamie Lynn wore a T-shirt emblazoned with the phrase “The Rumors Are True” while she flashed her engagement ring.

In April, the couple celebrated Jamie Lynn’s 17th birthday together while her parents looked after Britney in L.A.

Jamie Lynn passed her GED in February. She has said it “would be fun” to attend Louisiana State University.
