, they are divorced. The paperwork is viewed on the courthouse site, I saw it myself after following a link. It was either filed or finalized (I'm not sure of the terminology used) March of this year so shortly after Cinderella would have finished.
I feel for them, it must be incredibly awkward having to work so closely together and the filming when they had already filed or had separated must have been painful as well.
I'm thinking that Jonathon/Allison were in the same boat, already split up when this was being filmed and it's why things are so tense and awkward. They are just "acting" out the spit for the show.
