I have a friend who knows her. She's auditioning this year. Apparently she auditioned in 2014, although I don't remember it. The judges loved her and thought she was amazing but she was let go and scouted for last years series, however for personal reasons she couldn't audition. They've scouted her again this year and she's going for it. I loved her during Pop Idol. I actually thought she should have won.
It seems so long ago, XF would never do this now but there's no elaborate staging, no effects, no dancers, and she hasnt been given an OTT makeover (I guess?), she looks like an ordinary girl you'd meet anywhere.
