British singer Leona Lewis has vowed to confront her stage show fears and go on a world tour next year.

The "Bleeding Love" singer has admitted that she was terrified ahead of playing her first-ever full length concert in London this week but enjoyed the experience so much that now she plans a string of concerts around the world, reports contactmusic.com.

"I wasn't nervous until I got to the side of the stage, then I started shaking. I felt it went so fast and now I just want to do it again. I can't wait to tour next year," said Lewis.

"I was so worried about falling over in front of the audience. I have never done anything like that before. I was so nervous," she added.
