Jamie Lynn Spears has called off her wedding to boyfriend Casey Aldridge.

The younger sister of Britney Spears gave birth to the couple’s daughter Maddie Briann in June, but the young couple has been at the center of persistent infidelity rumors for months.

Jamie Lynn, 17, has decided she doesn’t need an official ceremony to enrich her relationship, pals say.

A OK! tipster tattles: “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.”

“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,” the insider adds. “Jamie Lynn knows she needs to make a living when she grows older, so she’s already discussing her career options with advisers. She wants Maddie to grow up in comfort.”
