Leo Varadkar was among those to congratulate Mairead Ronan after her Dancing with the Stars victory.
The Taoiseach was in the audience to watch the Dubliner beat out Love/Hate actor Johnny Ward and country crooner Cliona Haga to take home the Glitterball trophy.
Mairead became the first female celeb to win the top prize after a sensational performance on the final night.
And Leo was one of the first to pay tribute to the TV host, in addition to commiserating the unlucky losers.
He wrote on Twitter: "Great show. Great performances all round.

"Congrats to Mairead and John. Hard to luck to Cliona and Jonny.
"Looking forward to the next season."
Speaking after the show, Mairead, who gave birth to her third baby last August, told how everyone had advised her not to take part in the “gruelling” competition.
“This time last year I was in the audience, I was pregnant with Bonnie, I was supporting Anna Geary and I never dreamed that this would happen to me,” she told the Irish Mirror.

“The producer said ‘maybe you’ll be here next year.’ I said ‘not a chance I am 22 weeks pregnant,’ but they called me at the end of September. I was exclusively breast feeding, heavy and unfit.
“Everyone told me not to do it, that it is gruelling and you don’t want to go out and make an eejit of yourself.
"But the more they said it the more I wanted to do it.”
