No ego or drama involved. The host said very clearly at the start of the hour that SG was on because hers is the top selling line at the Q. Easy, peasy.
As for her remarks about "hurtful" comments, I suspect she wasn't talking about criticism of her designs but of all the rude, over the top and unnecessary comments made here about her personality and presenting style. Since she is the top selling designer on the Q it looks as if it's working for her, doesn't it?! And do any of you really expect or believe that a woman almost 60 is going to change her personality because some of you happen to not like it? What egos you all must have!
