Canadian superstar Celine Dion is desperate to have more children but is leaving it to fate to decide, because she doesn't want to undergo in vitro fertilisation (IVF) treatment again.

The Falling Into You hitmaker, who is the youngest of 14 children, would like her son Rene-Charles, four, to have a sibling, but doesn't want to interfere with the magic of conception this time around.

She says, "I don't know if I'll be lucky enough to become a mother again - only time will tell.

"I am already a mother. I am already fulfilled, so everything is great. If I were blessed a second time, that would be wonderful. "
