Brian Friedman has reportedly suggested that John and Edward Grimes could struggle with their vocals, if they were asked to sing a ballad on the show.

When asked if the twins were taking the place of a more talented act, Friedman, the show’s creative director told the Evening Standard: “Yes, but the thing is the public are voting for them.

“It’s going to show in the weeks to come if they do a ballad. Then the public will decide if they should stay.”
