Susan Boyle gave X Factor bosses a fright last weekend, when she turned up to do her performance sporting a new bright red hair colour.

The Britain’s Got Talent star reportedly tried to dye her grey hair at home, but messed up and ended up with vibrant red locks. ITV bosses called in top hair stylists to recolour her hair before she went on TV.

A source told The Sun: “It was chaos. “She was due on stage at 4pm on Saturday but at 1pm she arrived with bright red hair and a great big grin.

“The grey bits had completely soaked up the colour and were especially vibrant. There was no way she could have gone on stage like that.

“At one point they considered giving her a wig.”
