Celine Dion has hinted that her forthcoming world tour may be her last - as she wants to concentrate on motherhood.

The singer already has one child, six-year-old Rene Charles with husband Rene Angelil, but is keen to add to her family.

Dion insists any baby-making plans will have to wait until the end of her Taking Chances tour, which will see the singer perform over 100 dates in 85 cities.

She says: "If I had a child now I'd never want to go back on the road again."

Dion's tour begins on February 14 and finishes in January 2009.
