#4 Holly Holm - 111 days (Women's Bantamweight Champion)
On one fateful night back in November 2015, Holly Holm defeated Ronda Rousey at UFC 193 to become the Women's Bantamweight Champion.
To this day it is still one of the biggest shocks in the history of the sport, with Ronda being known as one of the most unstoppable fighters that the UFC had ever seen up until that point.
So essentially - it was a big deal, which is what made her eventual loss just a few months later even worse. Holm lost the belt to veteran Miesha Tate in one of the most entertaining finishes to a title fight in a long time.
Unfortunately, it set Holm on something of a downward spiral, as she has since gone on to lose yet another two fights since then. Hopefully, she'll be back to her best in due course of time.
We rewind a few years now to one of the biggest names to ever step foot inside the octagon.
