From a source:
The UGT cast you’ve been given and that’s floating around is completely off. There was talk of a Below Deck cross over and several ladies you mentioned were discussed.
However, producers loved the reaction to a recent UGT trip cast and they plan to continue to highlight some of those women along with some new, old favorites. Expect more “ex wives” than new on season 4. It will be filmed overseas and details plus contracts are currently being worked on.
