Married couple Brad and Victoria or...
Asian siblings Tammy and Victor will win Season 14! :)
I am rooting, however, for...
Gay father and son team Mel and Mike (yes, they're both gays!)
Mike is just the wractor (writer/actor) of School of Rock and Chuck & Buck (he directed the latter, too). He also wrote for Freaks and Geeks and Dawson's Creek. With a resume like that, how can I not root for him? :) His father is another interesting character. He wrote a book about Ninoy and Cory (Aquino) but that's nothing compared to his life story which you can read in Wiki. :)
