On the other hand, there are many people out there who have everything going for them - I've seen many genuinely talented classical pianists or opera singers who happen to be gorgeous.
It's usually not aa much of a prerequisite to make a career as a classical musician - although I suppose that good looking fellows do tend to get the lead roles. But talent is still required.
Similarly, in pop, Elvis who has been mentioned earlier was a lot more than just a pretty face. Of course, nowadays, his looks would be sufficient to build a career.
