I wouldn't personally describe her as a beautiful woman, she can take a good picture from some angles but I think she's pretty average. But rich, which helps. Each to their own, though. This isn't a particularly good angle as it highlights how close her eyes are, and she has an odd, pained expression. With her legs crossed like that, it looks like she's bursting for the loo. That's probably not what she was going for.
I think at this point she's either intentionally trolling the public (and making a lot of money from it), or she has really quite severe issues that means she really can't understand where she's going wrong. No sane person would have themselves announced when walking into their own private sitting room for a prearranged meeting with one visitor - especially if that visitor was a journalist and was most likely going to tell everybody. She's presumably been watching period dramas and thought it looked classy. But even without the bizarre hypocrisy of the "I despise the whole English aristocracy nonsense, I'm just a normal girl" routine, she looks like a complete idiot. And if she can't understand that, there must be surely something seriously wrong with her. Even Harry wouldn't behave like that. Not sure even Andrew would.
