Heavily pregnant woman who by her own admission isn't feeling well travels via ferry for hours and hours - I don't think so.
Also there is NO way at all she wouldn't have been spotted and tweeted/fb'd about. There's no hiding places on those ferries!
I thought that odd too. to get Marbella by car has to be via the aforementioned ferries. They are over nighters, the one to Bilbao is two nights.All I can think is, that the pink horse box can fly.
