As the final for The X Factor kicked off, viewers were left confused when they had no idea who the first guest performer was.
Becky Hill, a singer who found fame on BBC’s The Voice UK, opened the show with a rendition of Bring It Back by Moloko.
But when finalists Grace Davies, Rak-Su and Kevin Davy White joined her in the song, some fans couldn’t work out who Becky was.
Others speculated if she was another contestant that they hadn’t noticed before.
Even an audience member was seen mouthing the words ‘who is she?’ to the person sitting next to her as the camera was on her.
