The quote is still on the cover of the published book but it's missing from some of the publicity photos.
If I were a betting frau, I would say he's softly, gently cancelling her, not by a big public spat, but just quietly, behind the scenes. I'd further say it was something to do with the literary festival in September where he was supposed to interview her, she turned up hours late, and they had to fill in the gap with interviewing someone from a local foodie business who happened to be in the audience.
He hasn't interacted with her on Twitter since then, anyway.
And that's important to remember whenever we read Jack moaning about how TROLLS are "throwing nonsense" into her & SB's "lovely, close, little world".
Jack, it wasn't trolls that made you cancel glasto or all those media appearances, it wasn't trolls who made you be late for Jay or all those
other media appearances, it wasn't trolls who made you act up at the Edinburgh festival or in all those
other other media appearances.
And, while we're on it, neither was it trolls who made you accept inappropriate engagements such as the Catherine Cookson lecture, or the Community Housing Cymru keynote, nor trolls who made you do such a piss-poor job with Grifty Kitchen, nor trolls who delayed it by at least a year, nor trolls who failed to promote it, nor trolls who bathed in cash whilst admitting to having spent supporters' money on drink and drugs and sideboards, nor trolls who made you spend 120 hours a week lying and lying and lying about penknives and your son's sleeping arrangements to half a million followers.
None of that was trolls, Jack, it was all you.
