PICS: Mullingar’s finest, Niall Horan, heads list of celebrities on hand to witness Conor McGregor’s downfall

It was a disappointing night for Conor McGregor fans, even the famous ones.

The great and the good were out for Nate Diaz's second round submission of The Notorious in the MGM Grand. And they don't come greater or gooder than Gerard Butler Leonardo DiCaprio. The recently crowned Best Actor was cageside in Vegas, along with One Direction star Niall Horan, celebrity chef Gordon Ramsey and the wild child of American football, Johnny Manziel, who made his first appearance on Twitter in two months in honour of the event. Does Horan remind anyone else of a young Ramsey? https://twitter.com/UFCEurope/status/706335878109474816 https://twitter.com/TaraTaramahon/status/706304513389436928 https://twitter.com/JManziel2/status/706360258281607168 https://twitter.com/TaraTaramahon/status/706304513389436928 https://twitter.com/GerardButlerIn1/status/706363832319549440 https://twitter.com/Cris_Guia/status/706398364552679424 https://twitter.com/TheBMartin/status/706342579604819968
