WATCH: This four-year-old boy would give Riverdance a run for its money
Oscar has almost 18 trophies already and he only started competing in October 2015
He may be only four - but he's taking the Irish dancing world by storm.
Oscar Donnelly from Kilkenny has been dancing since he was three and started competing in October 2015.
In this incredible video he is performing a set dance called the Kilkenny Races at a speed of 110 BPM - which is something teenagers usually take on.
And watch out Michael Flatley as this little Irish dancing star is hot on your tail as he unbelievably made up the choreography himself.
Most dancers don't start in hard shoes until much later.
Since October he has already won four big championships including All Scotlands (U6 Champ), the others being in London and Dublin - accumulating roughly 18 trophies.
He's too young to enter the World Championships as you have to be 11 but he will be tough competition when he can.
Oscar's mum Annie Walters sent the video to Fusion Fighters as they are a fan of their Facebook page.
Annie said: "He totally loves watching Irish Dance video online, especially Fusion Fighters, so he will be jumping for joy knowing you are sharing his dancing.
"He shocks me Chris, he made the Kilkenny races up himself. He loves dancing to all music not just Irish music, he's always had great understanding of music and rhythm which I think makes him as good as what he is.
"It's just impressive that he does all this and he's still at nursery."
