I can't comment how how commonplace it is, but having worked in an office with many women there seemed to be a lot of animosity towards the more attractive women from the less attractive women. Could have just been that office.

Another friend who ran a support department told me she refused to hire a quite attractive candidate because she felt that the attractive woman would 'distract the men'. My personal feelings were that she liked being the only woman in the department. To be fair she also refused to hire candidates based on their age. We stopped talking shortly after that conversation.
