Toronto, Aug 19: Canadian pop diva Celine Dion is pregnant with her second child. Just like their first child, the second child has also been conceived through in vitro fertilization (IVF) at a New York clinic.

This will be the second child for the 41-year-old megastar with her 67-year-old husband-cum-manager Rene Angelil. The couple, who married in 1994, had their first child Rene-Charles nine years ago.

The pregnancy was confirmed Monday after test at the same clinic. The couple had sought medical help to conceive after Angelil was diagnosed with cancer in 1999. Since he was to be treated with radiation and chemotherapy which affect fertility, Angelil had frozen his sperm before undergoing the treatment.

In 2001, Dion had an intracytoplasmic sperm injection, in which a single sperm is injected into the egg. The couple planned to have two kids at the time. But one of the two fertilized eggs was frozen five days after conception and stored at the New York clinic at that time.

It is this frozen fertilized egg which will be the second offspring for the pop diva.

So rather than being twins, the couple's two children will now be siblings.

"Celine is very, very happy,'' Murielle Blondeau, a spokeswoman for Dion, was quoted as saying Tuesday. "Celine and Rene are full of joy. It's been a big dream for Celine to have a second child.

Local agency reports here said the sex of the child is not known.

The best-selling female artist of all time, Celine Dion has sold more than 200 million albums worldwide so far.

The youngest of the 14 kids born into a poverty-stricken musical family in Quebec, Dion was guided to greatness by Angelil who sold his house to finance the young girl's first album in 1981.

The French album went on to become number one in Quebec province, paving the way for her stardom.

Dion and Angelil became lovers but kept the affair under wraps, fearing that it will be frowned upon because he was 26 years older than her.
