Conor McGregor with Michael Conlan backstage ahead of his professional boxing debut at Madison Square Garden.

‘The Notorious’ Conor McGregor is in the house tonight ahead of Irishman Michael Conlan’s pro debut this St.Patrick’s Day in New York.

As promised, McGregor has shown up to walk his young friend out to the ring and show his support on a big night of Irish boxing on the country’s biggest day of the year.

In typical McGregor fashion his laugh is one of the first things you can both see and hear:

A busy scene by the looks of things there as Conlan starts getting warmed up. His walkout is not expected until at least 10pm ET (local time in NY) however.

McGregor has made himself well acquainted with the city of New York since flying in today.

Mentioning one famous New York citizen on social who was part of the movie ‘American Gangster’ earning the Irishman a lot of re-tweets already:
