From Slade's Twitt 25th aug (at least, we know rob& kris are alive...as we never see them !!!)

filipa_cullen I know right...i miss my daily Robert pictures to bright my day but he is M.I.A.....and so is Taylor Lautner.....whats up with that??

libenet the official version is that they are filming. yeah, but c'mon! 24h/day?? non stop?? WHERE ARE THEY??? come on! we see the rest of cast almost averyday (in vancouver, at airports...). I guess they're just avoiding papz. they probably think they have already give them much enough to deal with and talk about (with KOL and everything) and they just...hide now :S I really miss them, anyway :(
