CONOR McGREGOR joined in on the congratulations after Ireland won the Grand Slam on Saturday.
Inspired by Dan Sheehan, Andy Farrell's men won their first Grand Slam on home soil with a 29-16 win over England.
Taking to Twitter, McGregor paid tribute to the team as he hailed them on their victory.
He said: "Congrats @IrishRugby on winning the Grand Slam! Wow! What a St. Patrick’s weekend!"
Among the many, many, MANY subplots that came to be fulfilled on the night was Johnny Sexton chasing history on his final appearance in the Six Nations.

And it took just 18 minutes for the 37-year-old to do that, as he became the all-time leading scorer in the competition with a penalty.
That kick put him on 560, three clear of Ronan O'Gara, and would end the game on 566 after converting tries from Dan Sheehan (2), Robbie Henshaw, and Rob Herring.
He earned praise aplenty from fans on social media, while Andy Farrell hailed him as the greatest player Ireland have ever had.
The ex-England international said: "For captain Johnny here to finish his Six Nations campaign, he's been saying all week that this is what dreams are made of, it doesn't come around that often.
"It's unbelievably fitting that in my opinion the best player ever to play for Ireland is able to sign off on a Grand Slam on St Patrick's Day weekend, in front of his home crowd.
"Just, there's a lot of stars that have aligned over the last eight weeks and accumulated into this evening.”
However, while he can now call himself a two-time Grand Slam winner and four-time Six Nations champion, Sexton himself is already targeting the Rugby World Cup.
He said: “I’ve just said in the dressing room there, this is not the end. There’s plenty more in us.
"Roll on the World Cup, that's what we need to focus on next.
“That’s the goal, isn’t it? That’s what we spoke about building towards. This is a part of the journey and it’s very special, like the series in New Zealand was very special.

“You don’t have to have a poor Six Nations to go on and win the World Cup. When England won in 2003, they had a Grand Slam before it.
“We need to keep the feet on the ground and keep building.
“There’s a lot of guys who have missed this campaign who are going to come back and put pressure on the guys who have played in this campaign. And that’s what we need. Come World Cup time, we’ll need 40, 45 players, all at the same level, fighting for positions.”
