British singer Leona Lewis has reportedly turned to a hypnotist to help battle her fears over performing live.

The Bleeding Love hit-maker allegedly suffers from crippling stage fright and is said to be undergoing a series of therapy sessions in a bid to overcome her worries ahead of a planned world tour.

The singer is set to kick-off a string of massive gigs next summer and hopes the sessions will help prepare her for the challenge of singing to such large audiences night-after-night, according to British newspaper The Sun.

A source tells the publication, "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."

"(Her) bosses want to make sure her performance is as perfect and polished as an artist who has been around for years."
