The UFC Champion stunned the world last week, after he knocked out Jose Aldo after only 13 seconds.
He has achieved greatness in the MMA world, but does he have his sights set on something a little bit different?
Hollywood bad boy Vin Diesel shared a photo of him and the Dubliner on his instragram page saying, "Timing and precision...
The casting of the new XXX gets more exciting everyday. #Iliveforthiss**t."

Could this Crumlin Native be appearing in his next movie?
Well it wouldn't be the first time Vin Diesel has recruited a MMA Champion to join him on set.
The action star had MMA fighter Ronda Rousey appear in one of his projects too.
We will have to wait and see.
