Celine Dion has suggested that her upcoming world tour could be her last ever because she wants to concentrate on having another baby.

The singer already has a six-year-old son with husband Rene Angelil and has revealed that she would like to add to their family. But she has insisted that if she did become a mother again, she would not want to travel around on a tour.

Dion, who has put having a baby on hold while she performs over 100 dates on her Taking Chances tour, said: "If I had a child now I'd never want to go back on the road again."

Her forthcoming tour kicks off in February 2008 and will end in January 2009.
