Conor McGregor has written a poignant 90th birthday message for his late grandfather.
McGregor, 32, vowed that the pair would one day share a glass of the UFC star's own whiskey brand.
He wrote: "Happy 90th birthday to my Granda in heaven Christy “Jakes” Moore.
"The man who always told me growing up, that us Irish, us Irish are the World Champions at making Whiskey! I always wonder what he would think of my whiskey if he could try it!
"One day we will share a glass granda love you, miss you."
The Notorious also shared a picture of a bottle of his whiskey left on his grandfather's headstone.
McGregor has recently been celebrating the second birthday of his own whiskey, while holidaying with his family on the island of Corsica.
He made headlines last week after being arrested for allegedly exhibiting his private parts to a young married woman in the upmarket port town of Calvi on September 6 - a claim McGregor strongly denies.
Formal allegations were made to police last Thursday against McGregor by an as-yet unnamed complainant.
McGregor’s lawyer, Emmanuelle Ramon, said his client "vigorously denied any wrongdoing".
"He has been released before the legal end of police custody and without any judicial review," said Mr Ramon.
