Conor McGregor celebrates UFC 202 triumph over Nate Diaz by partying with Rory McIlroy and Niall Horan in Vegas

CONOR MCGREGOR blew away Nate Diaz in Vegas – then took to the town for a proper Irish celebration.

Notorious got his revenge on Diaz in a five-round epic, winning by majority decision amidst a raucous  atmosphere at the T-Mobile Arena.

And in true Belfast style, McGregor went out to celebrate and met up with Rory McIlroy and pop star Niall Horan for a proper knees up.

The Northern Irish golfer – a four-time Major winner – didn’t compete in this summer’s Olympics over fears of the Zika virus but will be a key member of the Europe Ryder Cup team later this year.

McGregor said after the fight: “The king is back! If you want this trilogy, it’s on MY terms.

“I came up to 170, now you’ll come back to 155 and we’ll finish what we’ve started.”

McGregor started the bout in superb form, dropping Diaz in the opening round, then repeating the trick TWICE more in the opening minute of the second as he dominated the early exchanges.

And the Irishman was relentless in the final round to win 48-47, 47-47, 48-47 on decision.
