Taylor Armstrong (Real Housewife. If you know her name, you know just how far ABC would be going in their quest for ratings. There is no shame floor. There is only a deepening hole.)Paul Reubens (Comedian. Heavily rumored. Was hanging around a lot last season and may have been actively campaigning for a spot.)
Ryan O'Neal (Boomerang -- was cast for last season and dropped out last-minute, bringing in Carson.)
Kerry Rhodes (NFL safety. Previously asked. Has been tweeting about whether he should go.)
Paula Dean (Cook. Seems to have been solidly approached by the show. Has health issues.)
Bar Refaeli (Model. Almost definitely approached, but has so many scheduling issues with her normal work that it may be impossible for her to find that many free hours. The show seems to be waiting on her ability to create time.)
Tim Tebow (NFL quarterback. Probably more viewer subset wishes than anything else. The network would love it, but would he? There's also been a micro-mention of Victor Cruz, but he's not well-known enough and kind of busy right now.)
Katie Couric (Anchorwoman. Has a talk show coming on ABC, so this would be an extended promo.)
A Random Kardashian (Brooke gave an interview which stated the producers aren't done tapping that well.)
