Please ABC ... NO MORE RE-TREADS!
But if Fleiss wants a known face or name, why not go for:
* a single, female star from an ABC TV show: lots to choose from from all the ABC-owned networks (Disney, ABC Family, Lifefime, A&E, ESPN, et al).
Most primetime shows finish taping in March or April, which could work out well if Fleiss' timeline is a summer season like B4. The Bachelorettes co-stars could come on the show to help/give advice and ABC could cross-promote!
* an ABC soap star (as all their soaps tape in NYC)and have the show there again
* a Dancing with the Stars dancer (too bad Karina just got engaged to Maksim)
