She was quite a beautiful Empress, that's true. She did have those lovers, and it's very likely that neither of her children ''with Alexander'' were his. He had bastard children as well, I've read, but they never had children together, more than officialy. Yet both seemed able to have children. This marriage which was hailed as such a great match quickly went sour, although he was closer to Elizabeth before his death, or was that before he disapeared to became Feodor Kuzmitch? There is a sad lack of biographies of her in English.
