Britain’s Got Talent semi-finalist Henry Gallagher has revealed he’s still not the girl.

The singer wowed the judges during the auditions with his original song Lightning, penned about someone at school he had a crush on.

But Henry has confessed that he’s not yet told the mysterious girl just how he feels.

“I still haven’t told her,” he confessed ahead of tonight’s live show. “When I did the audition Amanda said I would definitely get her, but when I went into school the next day everyone was looking at me to see which girl I would go up and talk to and I got shy again.

“I have written another song about her though, called Best Thing Ever about what it would be like to be with her.”

Meanwhile, Henry has revealed that he is the SECOND person in his family to make the BGT live shows.

His older sister Ellen Gallagher made the semi-finals in 2012, then aged 15, as part of girl group Be Minor.

They didn’t get through to the final but will Henry make it into Sunday’s live show?

“Seeing my sister do it just made me want to do it, seeing how much fun she had,” he explained. “But we are not competitive, she has been really supportive and just a good sister really.

Henry is set to perform in tonight’s live semi-final show for a spot in Sunday's live final.

Britain's Got Talent airs tonight from 7:30PM on ITV.
