The reporters sound a bit drunk to me. The guy seriously hopes it's not true. He keeps saying. "I hope it's not true. I seriously hope this is not true. I hope this isn't true." Alright buddy, moving on. In the end it's funny that in the end they all talk about whether they are attracted to intelligence or beauty.
Anyway, I would have interpreted it that intelligent people are likely to take better care of their appearances for reasons/ other variables not mentioned. (Intelligent people make more money and therefore can take better care of themselves, or intelligent people look better to attract better mates-they are intelligent enough to do so, or some other reason.) I didn't even think of the offspring thing until they mentioned it. Anyway, interesting, but seems unlikely.

If true, it could be that richer people can give themselves, or are given, more IQ and attractiveness. Both of which can be increased through money and spare time, especially attractiveness.
On the other hand, it could be IQ first, which is correlated with intelligence and skill, which are both correlated to financial success, which is correlated to attractiveness.
It could even be confidence caused by one trait increasing another. Seems less likely though. Higher IQ increasing the ability to make oneself conform to standards of beauty is a strong possibility too, outside of financial factors.
I guess even prejudice in favour of those regarded to be attractive could play a part. It's a strong prejudice.
The explanation in the video, selective breeding, seems a lot less likely. Attractiveness is way too linked to environmental factors, both in setting the standards and achieving those standards, and IQ can be increased through the environment, especially throughout old age.
