Romance on the Set: Dove Cameron is dating Ryan McCartan, who portrays her (Maddie's) love interest, Diggie.
What Could Have Been: It was originally planned to have just the twins, a separate project based around Joey Bragg was folded in.
The plot is a rehash of a pilot called Bits and Pieces which was picked up by Disney Channel but subsequently reformatted into this show. All the cast was exactly the same too, but with Dove Cameron playing a single role and Joey Bragg apparently getting the emphasis. Instead of a twin, the sister would've been played by Cozi Zuehlsdorff who now plays Liv's friend Ocean on the show. The Confession Cam elements are a holdover from the Bits and Pieces pilot, too.
