Celine Dion signed up to tour the world so she could show her seven-year-old son and her 80-year-old mother the sights she has seen over the years. The singer will embark on an extensive tour later this year (08) and admits the idea of hitting the road with two generations of her family helped her realise the gruelling trek would be worth it. She explains, "It's a privilege to see different countries and to see people living differently. "I think (my son) is at an age where he can understand, and I can give my mom the kick of seeing so many beautiful things in the world."
