LONDON: Singer Gwen Stefani feels she was cheating fans with her less than good performances on her recent tour because of her pregnancy. Stefani was five months pregnant when she performed her last show and she knew she wasn’t performing her best, according to contactmusic.com. She said: “All I could think of was being on the tour and being pregnant but not being able to tell everyone and not really feeling like myself. I found out I was pregnant right before I went on tour and I was like, ‘No, I have nine costume changes and high heels and bathings suits.’ I just wanted to say, ‘You don’t understand, I am really sick, and wanting to be like, `You guys, you don’t understand...’ I was four-and-a-half months pregnant the last show. It was a little bit ridiculous,” she said.
