The singer has revealed she's more frightened about going to the toilet than being a judge on The X Factor.

Rita said: “I always feel that when I go to the toilet that something's going to come out of the bottom.

“I have this thing where I think this tunnel must start from somewhere and sometimes I think, 'What if something comes out of the toilet?'

“That's been one of my fears. I always make sure I put the light on when I go.”

Is this a common thing?
