Dion Pregnant With Eight-year-old Embryo

The singer has revealed she is expecting her second child with husband Rene Angelil - a little brother or sister for the couple's eight-year-old son Rene-Charles.

And fertility specialist Dr. Zev Rosenwaks has revealed he implanted an embryo in the 41 year old's womb that had been frozen in liquid nitrogen since the in vitro fertilisation that helped her conceive Rene-Charles.

Dr. Rosenwaks tells People.com, "She came back to have the embryos transferred back because she wanted to have another baby."

And when the pregnancy test came back positive, she was thrilled.

The doctor adds, "She was very happy. So was Rene. They are both very thankful.

"She is feeling well. So far, so good. I look forward to hearing the fetal heartbeat. Rene and Celine are both looking forward to pregnancy that is a healthy one."
