Plenty of fans have already decided the celebrity behind Mushroom must be Charlotte Church. And the Welsh singer seemed to all but confirm it in the final tonight.
After a spell-binding performance which the panel almost unanimously decided it must be the Welsh songstress the final clue has proven it can only be the Crazy Chick singer. Speaking in northern accent, which many have decided is a red herring, Mushroom said they once stole the show from their 'modryb'.
For those who don't know Welsh, or had to Google it, 'modryb' is Welsh for aunt. Back in the 1990s Charlotte's big break came from a talent how in which she was supposed to be introducing her aunt.
