A law student, Andrea started losing her sight aged five and now only has 10% residual vision
One of the songs she will perform in the final is Sarah McLachlan's Angel, the same song she sang in the blind audition which brought audience members to tears and scored rave reviews
The Script star Danny said of the moment he chose her, "she changed the mood in the room – that's what megastars do. It was a great moment"
Andrea, who suffers from glaucoma, told the judges, "I came on the show for the very basic reason you couldn’t see me and I couldn’t see you. For once I am on a level playing field with all other contestants"
