Celine Dion can't wait to turn 40, because her life is getting better the older she becomes. The Canadian singer reaches the landmark next March (08) and she cannot contain her excitement. She says, "I can't wait. In my 30s, I became a mom and I had meaning in my life. Thank god there's something positive about getting older, something other than wrinkles, gravity and aging. I would never go back to my 20s. The best is yet to come."
