Jamie Lynn Spears is pushing ahead with her wedding plans.
A source said: "Jamie has her heart set on getting married to Casey, and wants her big day to be as special as possible."
Jamie Lynn, who gave birth to the couples' daughter Maddie seven months ago, has already chosen her wedding dress - a Monique Lhuillier gown.
Even though a date for the wedding has not yet been confirmed, the invitations have been ordered and a three-tiered chocolate cake arranged.
