Celine Dion's husband Rene Angelil has spoken out about their struggles to conceive another child, insisting they will continue to undergo fertility treatment.

Celine Dion has vowed to keep trying for another baby.
The 41-year-old singer and her husband Rene Angelil, 67, were told by doctors in August she was pregnant after undergoing a course of in vitro fertilisation (IVF) treatment, but days later were told it hadn't worked.
Despite more subsequent attempts at the treatment, Celine and Rene are refusing to give up hope of having a sibling for eight-year-old son Rene-Charles.
Rene said: "Dr. Zev Rosenwaks believed that the procedure/pregnancy took, but that wasn't the case. We found out some days later. We were shocked.
"We are living the reality of the majority of couples who have to use IVF. The process can be long and arduous.
"But today, we are full of confidence. Celine is more determined than ever. She doesn't let go."
The couple - who conceived Rene-Charles after fertility treatment - are now preparing for another course of treatment in New York this weekend.
Rene added to Canada's Journal de Montreal newspaper: "I admire all the women who go through such a tough process. Since April, she has undergone numerous examinations, multiple hormone injections and blood tests.
"Celine and I didn't get discouraged ... we put our faith in life and in the stars."

This is not the type of baby news we like to deliver: Céline Dion is no longer pregnant.
Last August, the golden-piped songbird and husband René Angélil confirmed that she was three months along with her second child after undergoing a round of in vitro fertilization treatments.
Unfortunately, that is no longer the case: Angélil confirmed to the Journal de Montreal that the 41-year-old Canadian chanteuse is no longer in the family way, as the embryo transfers—which took place in August and October—were ultimately unsuccessful.
Angélil said that both they and their doctor "believed that the procedure/pregnancy took, but that wasn't the case. We found out some days later. We were shocked."
But not deterred.
"We are living the reality of the majority of couples who have to use [IVF]," the 67-year-old hubby-manager said. "The process can be long and arduous.
"But today, we are full of confidence. Céline is more determined than ever."
In fact, the couple, who already has an 8-year-old son, René-Charles, is heading back to New York this weekend to see if the third time proves the charm.
"I admire all the women who go through such a tough process. Since April, she has undergone numerous examinations, multiple hormone injections and blood tests.
"Céline and I didn't get discouraged…we put our faith in life and in the stars."
