KSI Calls Wei Yamin Act Poo on Britain's Got Talent Episode 12

KSI drew immediate backlash on britain's got talent episode 12 after calling Wei Yamin's live semi-final act "poo" and telling him, "You can't polish a poo." The remark landed during the fourth live semi-final on ITV, where Amanda Holden had already buzzed halfway through the performance.

Wei Yamin Opens Live Semi-Final

Wei Yamin opened the show with a medley of 90s and 00s hits on the pipes while the stage burned behind him. Ant and Dec fronted the broadcast, and the panel featured Simon Cowell, Alesha Dixon, Amanda Holden and KSI, giving the exchange the feel of a live verdict rather than a routine performance note.

Amanda Holden also pressed her buzzer and told Yamin, "I think if you took away the pyrotechnics and everything else, you’ve got a man playing the U-bends, so that’s me, that’s what I think." She added, "I just don’t feel like that’s something I want to put in front of the royal family at the Royal Variety Show."

KSI’s On-Air Swipe

KSI answered in the bluntest possible terms, calling the act "poo" and saying, "No." when asked if he was impressed. He then followed with, "You added fire, still didn’t make it good. All I’m saying is, you can’t polish a poo." That turned a panel reaction into the night's main incident, because the criticism was no longer about the performance alone; it became a live clash over how far a judge should go on air.

Alesha Dixon called the remark "harsh," while Ant cut in with, "Alesha, a little bit of class wouldn’t go amiss right now." Dixon then tried to reset the tone for Yamin, saying, "Did you have a lovely time up there, you looked like you were having the time of your life!" and, "Ultimately, that’s what it’s about, I appreciate that you turned yourself into a human firework and I loved how passionate you were about pipes."

Simon Cowell’s Warm-Up Line

Simon Cowell took a split position, telling Yamin, "I kind of get it, I like you, I like the song, I liked it when you went higher, however, sometimes we say some of the acts are a warm-up, you literally were." That left KSI isolated on the harshest end of the panel, with viewer anger following fast after the broadcast.

The fury matters because the live semi-final format puts every judge’s reaction in the same frame as the act itself. KSI’s comment did not just dismiss Yamin’s pipes routine; it set off the kind of on-air dispute that can define a live episode more than the performance underneath it.
