The couple have signed a deal for a three-part series called Katie & Alex: For Better For Worse, which will follow the preparations for the big day as well as the ceremony itself.
Price and Reid's new programme is due to air over the summer and will also feature the pair's honeymoon.
In a statement, Price commented: "It's going to be great sharing this fantastic day with my friends and family. I can't wait to celebrate our love for each other again."
Reid added: "Katie and I are really looking forward to spending our special day with our family and close friends. Seeing her walk down the aisle again and being able to share it with the people we love will make this truly memorable."
According to The Sun, the couple will earn £600,000 from the TV deal. They first tied the knot in a private Las Vegas ceremony four months ago.
