Lucky young dancers in Hemsworth were choreographed by backing dancer for JLS Ess Green on Saturday.
The 21-year-old was teaching students at Dance Fusion dance school based at the Hub at Hemsworth Sports Centre.
Mr Green made it to the final of Sky 1’s Got to Dance competition with dance group The A Team.
Louise Rainford, who runs Dance Fusion, said: “It was an inspiration for the children to have Ess here. They were all gobsmacked.
“We’re hoping Ess teaching the children will improve their choreography and help us to be able to enter Got to Dance.”
Mr Green is also a dancer for Kimberly Wyatt, Pussycat Doll and judge on Got to Dance, and was crowned the world’s street dance champion in 2010.
He is currently starring in the London’s West End show ‘Some Like It Hip Hop’.
