1. Milli Vanilli – The French-German duo achieved phenomenal success with their dire dance-pop drivel in the late 80s and early 90s. Bad enough. However, their career soon turned to scandal when it emerged that the two former models never sung a note on any of their abysmal records. The shame caused their 1990 Grammy Award for Best Pop Act to be removed while Arista Records deleted their debut album before dropping them. It got worse – 21 separate lawsuits were filed in the US against the group and their management which resulted in an agreement to refund everyone who bought a Milli Vanilli record or attended one of their botched concerts. Unquestionably the worst pop act ever.
