6. Lita
Subject of the most infamous infidelity in WWE history, Lita's affair with Edge instantly made her one of the most controversial divas ever to set foot in the ring. Former boyfriend Matt Hardy was released, only to be rehired a few months later as a result of massive fan demand. His emotionally-charged feud with Edge fizzled and died, but Lita's career was transformed forever. Fast-tracked to the main event scene as Edge's equally nefarious girlfriend, she landed herself a supporting role in high-profile feuds with John Cena and Mick Foley. Her most infamous onscreen moment was the 'Live Sex Celebration' of Edge's first WWE Championship reign - the highest rated Raw segment of the year - in which Cena interfered to give the diva a thunderous Attitude Adjustment.
