Two More Acts Through To BGT Final
The young dance troupe and music act got the nod - with the band coming top in the public vote and the dancers only going through after a split vote from the judges caused the decision to revert to the public vote.
Joseph Hall had also finished in the top three and had been picked by Amanda Holden and Alesha Dixon, but because David Walliams and Simon Cowell plumped for Pre-Skool, the vote decided the outcome.
Luminites said the news was "absolutely incredible", and added: "Thank you so much."
The acts in tonight's fourth semi-final are AJ and Chloe, Alex Keirl, Francine Lewis, Asanda, Clubtown Freaks, James More, Poppin Ron, Chasing The Dream and The Shockarellas.
The show will be broadcast on ITV1 at 7.30pm and the results at 9.30pm.
We told you yesterday how J-Lo's guest spot on the show had sparked complaints.
