I know I’ve covered this topic quite a bit but Princess Catherine is in line to become a future Queen of the United Kingdom so it doesn’t seem that unreasonable to politely ask why it is that the last time we can be certain we saw her was December 25th 2023.
Dame Edna made a similar joke about when he met Diana.
Apparently this was based on a joke by Dame Edna Everidge, and unlikely to be a genuine cry for help.
