VIDEO: Conor McGregor is in full-on party mode as he raps at his after-party in Las Vegas

A well-deserved celebration...

To say that Conor McGregor will be letting off some steam is a bit of an understatement.

The newly-crowned champ is partying at an exclusive event at Foxtail SLS in Las Vegas to celebrate his victory over Jose Aldo at UFC 194.

It looks like great craic.
