While I agree that Princess Charlène could have used her time in Monaco better to master French by now and to take advantage of other educational privileges like private tutoring, there are a couple of points I would like to make:
• She is fluent in Afrikaans. Many years back I saw an interview with her on an Afrikaans TV news bulletin in SA, related to a swimming event she had participated in. As I mentioned before, speaking Afrikaans gives her an advantage to be able to communicate with Dutch- and Flemish-speaking folks too. (Sorry, I cannot find a link of this – it was a long time ago before she moved to Monaco.)
• The reason why she was 'not allowed' to answer questions from the media last week in SA is possibly because they (the media) can be very insensitive, and would no doubt have questioned her on her feelings about the latest scandal. It takes a very media-savvy person to deal with such a, erm, 'delicate' situation – and she certainly lacks skills in that department, admittedly.
• She does seem to be able to at least understand some French. In my own experience, while traveling in France, I was better off sticking to English because my bad, broken French did not go down very well. Imagine practicing your French in the media spotlight! I hope that she makes an effort though, and that her French will improve to a level where she would feel comfortable speaking it in public situations.
• Indeed, she can certainly not be considered as an intellectual. But the experience and know-how she acquired from many years of traveling internationally while competing in swimming tournaments – not to mention the dedication it takes to be an Olympian athlete – provided her with a different kind of skills set that will come in very handy.
• Although there's no black-on-white evidence that she has had cosmetic surgery, I believe that she has. But she was always pretty, and really didn't need it. Whatever her reasons, it was her choice. But she certainly isn't only pretty now as a result of it, as implied.
• I think (hope) that now that they're married and her role is defined, she will use her time better to not only be considered is Prince Albert's 'arm candy'... Apart from producing an heir she has to dedicate time to become fluent in French, enrich herself with knowledge in many other areas, build relationships, continue with her commitments to various charities, hopefully launch Monaco's first Fashion Week – all the while behaving like a worthy role-model and dress for/look the part.
For those of us who do like Princess Charlène and believe she has potential, it is important to not be oblivious to her shortcomings, as pointed out by SandwichSheik. She is certainly not the fairytale princess some make her out to be. But she also doesn't deserve some of the cruel criticism. I wish her all the luck in the world. She's going to need it!
