Please note that episode 20 is called "The Choice" - it is the episode in regard to which that spoiler was posted, about House having sex with someone and letting Cuddy know which of them he chooses. The majority of us refused to believe it, because it seemed improbable and not trust worthy, and yet, here is the title...
Personally, i still believe that that spoiler was based on speculation made upon the title - i think it's way easier for someone to find out the title of an ep, than the content of it in such detail. Whichever it is, i PRAY that it all turns out good for Huddy. A lot of signals point towards it (David Shore and Michael Weston interview, for instance), i hope it's not much ado about nothing...
