Don't watch it...but am aware of the general "idea" of the show
Seems you need a wide range of differing characters (custom made formula for here) who will either bounce off one another ....or jump into bed.
Lets go with 8
(1)LVT.............Had to be included obviously
(2)John Dunne ........See above for reason
(3)Tom Sand........Some good big brother chair confessions while eating my dinner
(4)Saul...............Couple of months apart will be a great test of his new relationship
(5)SophieX..........A temptress for the 3 above (And there has to be loads of skeletons in that closet that the paps will dig up)
(6)Samlad...........The token dead career that needs some help to resurrect
(7)Claudia........week number 6 entrance in the middle of the night to confront a certain someone about his goings on
(8)Annabel...............Ratings are what the show is all about after all
You can choose better?
