That doesn’t mean the 3 biggest judges knew anything about her, only that the first rung of judges knew she sang well and encouraged her to perform. She tried out for the X Factor and she said, “They took one look at me and decided I didn’t have the X Factor”. She said if she didn’t do well on Britain’s Got Talent that she would give up singing for the rest of her life. Glad it worked out differently!
Doesn’t the show do auditions in varied places, like AI? She could very well have been encouraged by someone who’d contacted the program and asked that she be auditioned, knowing her lovely voice. Nothing sinister about that.
