Port Talbot dance troupe Pre-Skool impressed the judges on last night's Britain's Got Talent.
The youngsters were inspired to enter the competion by siblings who got through to last year's final with Nu Sxool.
The 13-strong group - made up of children aged five to eight - was choreographed by Terry Michael, who was also behind Nu Sxool's successful audition. Pre-Skool are through to the next round after each of the four judges said 'yes.'
Judge David Walliams told them: "I thought, I really hope their dancing lives up to how cute they are, and it did. It was fantastic."
An artist from Ebbw Vale who wowed the judges on Britain's Got Talent by creating portraits out of marmite has now paid a cheeky tribute to another ITV talent show star - Rylan Clark.
Nathan Wyburn, who first showed off his skills at portraying celebrities with unusual materials on ITV Cymru Wales, used a tube of fake tan to paint Essex lad Rylan, who finished fifth in last year's X Factor.
"It was inspired by Rylan's obsession with fake tan, I thought it would make a very fitting portrait", Nathan said. "When I presented it to him he claimed it was the most unique gift he'd ever been given, and that it meant more than any cars or clothes he'd received."
Nathan, who is 22 and a fine arts graduate, has used Marmite to paint portraits of the Queen David Beckham, Michael Jackson, Kate Middleton, and our very own Andrea.
