Conor McGregor sang a rendition of "Whiskey in the Jar" as he paid tribute to fellow Crumlin man Phil Lynott this weekend.
The Notorious posted a video of him signing the Thin Lizzy classic hit with US chat host Jimmy Fallon.
McGregor and Fallon came together for an Irish-themed duet in March but the UFC star posted a new clip of their singsong to celebrate his son Conor Junior's second birthday on Sunday.
He wrote about the video: "Here is a little “Proper in the Jar” with Jimmy Fallon to kickstart this Bank holiday weekend!
"My son turns 2 this weekend so we are celebrating! I count my lucky stars everyday for this life!
"I am feeling that great Friday feeling today, oh yes! I hope you all have a Proper weekend with the ones you love!
"Shout out Phil Lynott of Leighlin Road, Crumlin Dublin 12 also. A black Irishman from Crumlin in the 60s, that grew up to be become a true rock ‘n’ roll icon!
"I grew up right around the corner on Clonmacnoise Road. Up the Proper 12!
Happy Friday everyone!"
Conor's partner Dee Devlin replied to the video: "Yes!!!"
Conor Junior was the couple's first child two years ago before they had a baby daughter called Croia in January.
