You know, I do think this is - odd. He must as Couch says be in the UK to film the Graham Norton Show. So these tweets were at 1 and 2am. Plus he thanked Taffy and then deleted it. That is very hyper and he doesn't usually tweet at 2am GMT. He has also been sharing the love on IG twice - at 2.30am! He sounded either nuts or a bit drunk - "sincere thanks...a huge honour" - for a magazine cover! He has had plenty of those in the past and we haven't seen these outpourings of emotion.
I have to say, I don't think he's entirely well in himself. He has had a tough year. He was not a major star but was usually spoken of respectfully in the media. Now he has become a laughing stock over Tayto, and as a result is spoken of much more critically, even though he has reverted to his previous behaviour. So he wins a GG or does an article and nothing is quite as he envisages. That has to have had an effect on him. We have always known he reads his twitter tag and cares deeply about such things. He has never been one to let it all wash over him - and there's been a lot to deal with recently.
