Proud mum Sharla Johnson confesses to being “sick with nerves” about her son Jamie’s appearance on The Voice tonight.

But although 19-year-old Jamie, from Gillingham, is facing the biggest night of his life, competing for a place in the final of the TV talent competition, she is confident of one thing.

The 43-year-old community nurse said: “He won’t forget Mother’s Day on Sunday. Whatever happens on Saturday, it will be the same as ever.”

Mrs Johnson, Jamie’s dad Matt and sister Jessica, 17, will once again be in the audience sporting their Support Jamie T-shirts.

And if he gets through, there will be another cause for celebration as today is also Mr Johnson’s 45th birthday.

Mrs Johnson said Jamie started singing around the house from the age of three and gave his first impromptu performance in his grandparents’ garden when he was just eight.

She said: “He’s always had a good voice and I have always had every faith in Jamie, but when he was young he was shy and used to get panic attacks.

“We are all amazed where he has found this confidence and overcome his nerves.”

Over the past few weeks he has been staying with fellow Team Kylie semi-finalist Lee Glasson in a London apartment, and his hectic schedule means he has only been able to return to his family home once.

Mrs Johnson said: “He wanted to stay out of the spotlight, so we just went out for a quiet family meal.

"When he went back I packed him up with his favourite home comforts, fruit juice and chocolate bon-bons.

"The family are getting used to being in the spotlight here in Medway.

Mrs Johnson said: “Both myself and Jessica get embarrassed when we are shown on camera because we get so emotional. But I think my husband Matt wishes he was on stage with Jamie getting hugged by Kylie.

“I have just popped to the supermarket where people come up and say ‘you are Jamie’s mum’ and Jessica gets recognised in the cafe where she works.”

Jamie said: “My family have been so supportive.”

The Voice semi-finals are on BBC One tonight at 7pm.
