Paris Hilton syndrome
The Paris Hilton syndrome refers to the gleeful pleasure that some people get when some essentially harmless prominent or attractive person experiences humiliation; as was the case when the Hilton heiress and model Paris Hilton was outed in the widely-disseminated and infamous sex video.  It is essentially one form of schadenfreude.
Meg and Candy enjoyed the fall from grace of pop princess Britney Spears; another manifestation of the Paris Hilton syndrome.
