But we don't know do we. Yesterday everyone was convinced it was Vine.
I reckon that may have been sparked by an eager person who saw a press release oddly saying that he was being REPLACED by somebody else on his TV show, when she was only standing in for him for a week whilst he was on holiday - and it was from two or three weeks ago and he's since been back.
I think there are an awful lot of inexplicable 'coincidences' stacking up against the current man if it isn't him.
This is just my personal feeling, but I find it very surprising for a man of his age and demographic to put his (very obvious) pronouns in his SM bio - at the very beginning before everything else, as well. Apart from anything else, he's on the BBC and always referred to as 'he' by his colleagues - I think all of us would know very well by now if he wanted to use non-sex-based ones.
