Leona Lewis is having hypnotherapy to boost her confidence.
The Bleeding Love singer's mentor Simon Cowell has arranged for her to be treated by celebrity therapist Paul McKenna to banish her nerves ahead of her proposed 14-month tour.
A source said: "Seeing as Leona is on the path to becoming a global touring powerhouse, no corners will be cut.
"She already has bags more poise and confidence than she used to but she's a natural born worrier.
"Bosses at Syco want to make sure her performance is as perfect and polished as an artist who has been around for years."
Leona - who shot to fame after winning UK TV talent contest The X Factor - is not the first celebrity to be put into a trance to beat their problems.
Former Spice Girls star Mel B underwent treatment to calm her nerves before starring in raunchy Las Vegas burlesque production Peep Show earlier this year.
She said: "I'm getting hypnosis. I'm seeing a guy called Anthony Cool, who performs a show in Vegas too. I'm doing this just in case I get any last minute nerves - you know, in case I can't remember the lyrics or the moves. He's going to hypnotise me as soon as I get there."
Eva Mendes had hypnotherapy to overcome her arachnophobia - an irrational fear of spiders - which started when she was a child.
The actress - who admits her fear became so bad she would not even sleep in a room if she had seen an eight-legged nasty in there earlier - said: "There was no swaying clock or anything like that - so I was a bit disappointed by that. I don't know what she did but it really helped because now I will see one and I will be cool with it."
