Doesn't have to be celebrities but I don't have my own to share.
Harvey Weinstein for obvious reasons.
Michael Barrymore for not coming clean about the man who died at a party he was at.
Rolf Harris went from beloved childhood hero to reviled paedo.
Duffy because she rode a bike singing about Diet Coke.
Michael and Janet Jackson. Michael for all the rumours and Janet for her Super Bowl performance.
Have to see if she manages to ride through this but possibly Zoella for her expensive calendar and the debacle of the Youtubers event.
David Cameron for resigning (I don't know many who held him in high regards anyway to be fair).
