There's a reason why she was PWI's No. 1 female in 2010, as well as WWE's Diva of the Year, and I'm pretty sure it's not because of her marriage.
Michelle McCool tops my list because not only is she hot, but she is, without a doubt, the best female wrestler in the WWE today.
Following her time in the Diva Search, McCool was featured very little until she began to bring her former job into her current one, adopting a gimmick as a teacher. While she wasn't given many opportunities in the ring, she was a valet for "Teacher's Pets," and helped them to a Tag Title match, although they fell to Brian Kendrick and Paul London.
Following an injury, she was in a series of matches to determine the top diva on Smackdown, which she would win. In July of 2008, she would beat Natalya to be crowned WWE's first Divas Champion.
After winning her second title, she teamed up with Layla to form Lay-Cool (see Layla slide; I won't go over all of it again), and become the dominant divas in WWE. She would also become the first Unified Divas Champ, defeating Melina to unify the Women's and Divas belts.
In conclusion, Undertaker, you are one lucky man.
