Holly Holm is just weeks away from facing Miesha Tate in her first UFC title defence.
The former champion boxer will take on Tate at UFC 196 in Las Vegas on the same card as Conor McGregor and Rafael Dos Anjos.
It will be a huge test of how powerful Holm really is, after she ruthlessly dispatched undefeated former champ Ronda Rousey with a kick that turned the MMA world on its head.
We've been watching that brutal knock-out head kick over and over again after the UFC dropped the full fight video of Holm vs Rousey from UFC 193.

But if anyone thought that was just a flash in the pan then just check out her first true knock-out in MMA.
Holm has won seven of her 10 pro MMA fights by TKO or KO - but this was the first time she put an opponent's lights out in one.
It came in a Legacy FC bout with Allana Jones - and we're sure Ronda Rousey will be able to relate to how powerful that left kick really is.
She shoots with a lovely right hand fake to draw out Jones' guard and then lands the head kick with devastating precision.
It's a shot Tate will surely have to be wary of come March 5...
Here is the fight in full...
