Big-voiced singer Celine Dion is looking forward to the end of her Las Vegas concert contract, because she's planning to conceive a second child.

The MY HEART WILL GO ON hitmaker, 37, and her manager/husband RENE ANGELIL welcomed their first child RENE-CHARLES in 2001 after years of in vitro fertilisation (IVF) treatment and are eager for the tot to have a little brother or sister before Dion gets any older.

Dion, who has been performing at Sin City's Caesar's Palace since 2003, plans to go through another course of IVF after her contract ends in 2007.

She says, "I'm approaching 40 years old, and I have to tend to that.

"This frozen embryo that is in New York is my child waiting to be brought to life."
