#1 AJ Lee (Three reigns, 406 combined days as champion)
In some ways it is ironic, that the woman who liked to be labelled the anti-Diva is the most successful Diva's Champion of all time and will always be synonymous with the now defunct belt. AJ Lee captured the first of her three Diva's Titles at Payback 2013 when she beat Kaitlyn in an impressive encounter, which was easily the best bout of Kaitlyn's career at that point.
Lee's first title run was her most successful as it lasted a whopping 295 days, breaking the record for longest title run before it was eventually surpassed by Nikki Bella. She dropped title number one to Paige in a memorable match-up on the post WrestleMania XXX Raw. She reclaimed it two months later before losing once more to Paige in another entertaining encounter at SummerSlam.
Lee was not without the butterfly strap for long as she regained it a month later in a triple threat bout with Paige and Bella to become a record equalling three time champion, before she was upended by Bella at the Survivor Series. Lee retired from the ring four months later but left a lasting legacy with the Diva's Championship.
