Report: Celine Dion Pregnant with Embryo that was Frozen Eight Years Ago

Celine Dion's doctor is revealing details behind the star's pregnancy, according to a new report.

People.com reports that Celine's physician, Dr. Zev Rosenwaks, says the star became pregnant for the second time using an IVF (in vitro fertilization) procedure which involved transferring an embryo that was kept frozen for eight years in liquid nitrogen.

Celine, 41, kept the embryo frozen from the time she tried to conceive her first child, René-Charles, says People. She decided to try for a second baby in 2007, Dr. Rosenwaks adds.
