Jamie Lynn Spears is putting off plans to marry boyfriend Casey Aldridge so she can focus on being a "hands on Southern mother", it's claimed.

The youngest Spears reportedly planned to marry her baby-daddy following the birth of their daughter Maddie in July 2008 - but after a change of heart, the wedding is off, says a U.S. publication. 

A source close to the Spears clan tells OK! magazine, “The wedding’s off. They are still in love, living together and very happy, but they have no plans to get married.

"Jamie Lynn has everything she wants and feels no need for a ring and piece of paper.”

And it seems for Jamie - unlike big sis - her time in the spotlight could well and truly be over.

The source adds, “She has told friends and family she’s never coming back to Hollywood. She feels that part of her life is over.

"Jamie Lynn enjoyed every minute of doing Zoey, but since she’s had Maddie, her life has changed completely.

"She’s happy being a real hands-on Southern mother and hopes to continue that for years to come with Casey right by her side."
