She’s always been pro-Meghan, so that’s nothing new. Anyone who notes that MM is a “famewhore” she then insinuates that they’re racist.
Andrew has a shady past, but the only tiara post I recall of hers recently was Eugenie wearing the York tiara.
Really, if you have an issue with her, then you should write to her about it. It seems to me that she does not pay much attention to celebrity news/gossip, so I don’t think she notices the “dodgy stuff” like other people such as AHPF does.
