Former Pussycat Doll Nicole Scherzinger says exercise not only gives a boost to herconfidence, but also makes her creative. The 33-year-old singer says staying in shape gives her power,reported Daily Mirror. "Staying in shape is where I get my power from. It keeps my temple strong.Physically it helps because you feel more confident in your clothes and how you hold yourself, but it'sall mental for me. If I don't work out I actually look more slender as I don't have as much definition, shesaid. "But exercise is when I'm creative, where I get my ideas. I think of songs, I think about my tours andwhat I'm going to do on stage. Exercise gives me confidence because if I can get my butt out there, feelsome pain and sweat then, world, I'm ready," she added.
