CONOR McGREGOR shared an old photo of him as a boy before St Patrick's Day.
He is a 33-year-old Irishman who has won UFC World Titles in two weight classes.
Conor McGregor is excited to celebrate St Patrick's Day
He was high spirits Tuesday night, ahead of Ireland's largest party holiday of the season.
This year's St Patrick's Day will be on Thursday, March 17.
McGregor clearly loves the Paddy's Day parade. He tweeted a young picture of himself attending the event.
McGregor looks completely different with his blonde hair, so it's hard to tell if he is McGregor.
He was in a buoyant mood at the time and hasn't lost his excitement for the parade as he grows up.
He also tweeted the following: "It's almost the time for the St Patrick's Day Parade again guys, who's thrilled? 
."
McGregor made headlines last week after he said he was interested to buy Chelsea Football Club from Roman Abramovich.
UFC star UFC tweeted that he had put forward a PS1.5 billion bid for West London's outfit.
McGregor's proposal was viewed as insincere by many, given his social media bravado.
He then confirmed that he was interested in buying Chelsea from Russia.
He said: "I do not speak in jest. As I said, I am looking into this. Celtic from Dermot Demond, Manchester United form the Glazers and now the newly up for sale Chelsea football team. All being explored.
"It is my future to buy a football franchise, make no mistake."
FOOTBALL CLUB OWNERSHIP
McGregor's PS1.5bn offer is believed to be an attempt to get the PS3bn Abramovich wants.
But, the UFC man may have offered a formal invitation that is more than he claims on social media.
Sky reports that McGregor's management firm Paradigm Sports works closely with McGregor Sports & Entertainment & Empowerment IP Capital, which is led by Stephen Duval, a sports financier.
McGregor's group is also said to be in talks with an asset management company that could lend a hand financing a deal this large.
