Singer Celine Dion will end her stint on the Las Vegas concert circuit as she’s planning a second child. Celine (37) and her manager/husband Rene Angelil are keen for their first born – Rene-Charles (four) who was conceived through IVF treatment – to have a sibling. Celine has been performing at Sin City’s Caesar’s Palace since 2003 and 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.”
