Brian McFadden belted out Westlife hit Flying Without Wings as champion James Jordan celebrated his victory at the Dancing On Ice wrap party.
McFadden, who is not part of the forthcoming reunion tour, showed off his singing skills with the hit 1999 song, urging the crowd to join in for a spot of karaoke.
Wes Nelson, who finished second, shared videos of the sing-along on his Instagram, while Jordan's wife Ola shared a clip of her husband downing a bottle of wine.
“This is how you party after you win!!!!” she wrote on Instagram.
Former Strictly professional James was crowned champion on Sunday night after scoring two out of three 40s with professional partner Alexandra Schauman.
He broke down in tears as hosts Holly Willoughby and Phillip Schofield announced their names, with James crediting his win to “digging so hard for his partner”.
The pair achieved perfect scores for their favourite routine as well as their take on Jayne Torvill and Christopher Dean’s iconic Bolero.
James spent six hours with a physio ahead of Sunday night's final after crashing onto the ice and injuring his shoulder.
He beat off competition from Love Island star Nelson and his partner Vanessa Bauer to lift the trophy, despite the couple having received three full house scores during the show.
Former X Factor star Saara Aalto finished third in the competition, having been eliminated before getting the chance to perform the Bolero.
Dancing on Ice will return to ITV next year
