X Factor singer Danyl Johnson is said to be on the verge of an emotional breakdown and ITV bosses are so worried that they called in a psychologist to evaluate his mental state.

A source told Now magazine: “Danyl’s suffered from stress-related illnesses in the past, which were so bad he was in therapy.

“He had a nervous breakdown in 2004 after his boy band NV split. He really struggles with rejection, so he’s probably in the wrong industry.”

Danyl was visibly upset on the live show two weeks ago after he faced a week of negative media attention, including reports that he was bullying other contestants.

The insider added: “The show’s bosses are aware of his past and since all the fuss over Susan Boyle on Britain’s Got Talent they’re switched on about dealing with vulnerable contestants. They’ve been keeping an eye on Danyl.

“They called in psychologists this week and they’re happy for him to continue now they’ve assessed him.

“All the contestants had psychological testing this year to ensure they could handle the pressure.”
