The 37-year-old singer said she plans to begin in vitro fertilization treatments at a New York clinic after finishing her work at theLas Vegas (search) venue, a gig she started in 2003.
"I'm approaching 40 years old, and I have to tend to that," Dion told the French Entertainment magazine Tele 7 Jours. "This frozen embryo that is in New York is my child waiting to be brought to life."
The Canadian-born singer and her manager-husband, Rene Angelil, had their first child, Rene-Charles, in 2001 through in vitro fertilization after years of trying.
Dion said she has 350 shows left to perform at Caesar's Palace and has no intention of giving up singing, but also has other interests.
"I would love to make a film," said Dion, who was in Paris to promote her latest album. "I want an Oscar!"
