Her decision to select Katie appears to have sparked angry comments from viewers, who were stunned that Cheryl let Nigerian Gamu go, but kept “drama queen” Katie.

It has since been widely reported that the shows producers told Cheryl not to put Gamu through to the live finals on account of immigration issues. This has since been denied by an X Factor spokes person. The statement now leaves a lot X Factor fans still wondering why the very talented Gamu was not selected to go through to the next stage of the competition.
