Well, I've just watched todays show and Helen wasn't on it, in fact she wasn't even mentioned at all.
As chilledbootz said on another thread, she's hardly been on at all recently and it's quite worrying.
However, I have just read a post that hallie made on TalkBB where she says how she has heard back from GMTV after having made in enquiry about Helen, and that she was told that Helen is still very much part of Lorraine's team and that she has just been of doing 'various projects'. So it looks as though Helen will be back soon. Let's hope so.
