"And when you chose Tyler Perry as godparent to your daughter, what was it about this multi millionaire, a man you barely knew, that placed him straight into top spot for the role?"
Same could be said of many of their wedding guests. At the time, I naively thought that MM knew the Clooneys, Oprah etc through being an actress. Of course, one could say the same in reverse - 'Tell me, Ms Winfrey, why did you accept an invitation from a minor actress you didn't know, to attend a wedding in a castle in the presence of royalty?'
They got on famously well with ER II.
Apparently, once when Michelle Obama was in London with her daughters on a private visit, the Queen heard they were in town and invited them to tea at BP. This was when Obama was no longer president, so no diplomatic courtesies involved, and absolutely no reason why the Queen should have done this if she hadn't genuinely wanted to.
The story, as I recall, came from Michelle herself after the Queen died, so presume it's true.
