Harry Smallman from Flintshire is one step away from winning the BBC The Greatest Dancer show alongside his partner Eleiyah Navis.
The dance duo famously brought tears to Cheryl Tweedy 's eyes in the first live episode of BBC show The Greatest Dancer.
Last week, after taking on the circus challenge, they achieved a 97% audience score - the highest ever in the show.
The pair, the remaining competitors from Cheryl's squad on the show, were entered for the contest by Jelli Studios principal Jennifer Ellison, who had previously encouraged them to compete in Dance Mums.
The winner of the competition will win £50,000 and will perform on the Strictly Come Dancing stage.
Harry's proud mum Claire Smallman said: "I am both nervous and excited about Saturday.
"We had a farewell party for Harry and Eleiyah last night at Jelli Studio before they went to London to prepare for the show last night.
"They've been working really hard all week, Cheryl has been working with them on a dance for Saturday night."
Claire continued: "Cheryl is really lovely and is exactly the same as she comes across on the TV, she says Harry and Eleiyah are insanely talented which was lovely to hear."
Harry started dancing when he was around 10 or 11, and despite his talent his mother says he remains very humble and is quiet when he's at home in Connah's Quay .
"He's very quiet at home but I'm told he's quite the comedian when he's at college," said Claire, who works for the NHS as an administrator.
"But his teachers tell me he's very humble as if he doesn't quite realise how talented he is.

"Harry is very lucky because he's also got an amazing singing voice too, and we don't know where it comes from but certainly not from his father and I."
Claire urged North Wales viewers to vote for Harry and Eleiyah on Saturday night.
"It would be nice if people voted for them as Harry's dancing all started in Flintshire," added Claire.
