The unthinkable has happened. Ronda Rousey lost her UFC championship when she got knocked out by Holly Holm in their title fight at UFC 193 in Australia Saturday night.

It took just :59 seconds into the second round when Holm delivered a kick to the side of Rousey's head that dropped her to the mat. Holm jumped on her and started throwing hammer punches when the referee jumped in to stop the fight.

Rousey came out aggressive as she always does which on this night proved to be her downfall. The former boxing champ Holm was able to land a couple punches to the face of Rousey who seemed to walk right into them as she attempted to attack Holm in the first round.

Stay tuned for the re-match.
