According to In Touch magazine, Jamie Lynn Spears is set to marry fiance Casey Aldridge, who is also the father of her daughter, Maddie, 7 months. Spears has already reportedly picked out her gown and cake, and has ordered the invitations.

The wedding will happen, despite earlier rumors that Jamie Lynn had kicked Casey out of the house and called off the wedding after allegations that he had cheated on her showed up in the tabloids. The couple denied those rumors.

Jamie Lynn, 17, is said to have chosen a gown from designer Monique Lhuillier, and has picked out a three-tiered chocolate cake. All that's left to do is for the couple to pick a date.

Sources say that despite claims that Casey cheated on her while she was pregnant, Jamie Lynn hopes that by getting married she can keep their young family together.
