Pop superstar Celine Dion is expecting her second child with husband and manager Rene Angelil in May. A spokeswoman for the Quebec artist confirmed the pregnancy to CTV News on Tuesday morning.

Dion and her husband Rene Angelil found out about the pregnancy on Monday after the best-selling singer underwent fertility treatment in New York.

The sex of the baby was not immediately known.

"Celine is very, very happy," said Murielle Blondeau, a spokeswoman with the Bureau de Francine Chaloult, which handles media relations for the singer in Quebec.

"Celine and Rene are full of joy. It's been a big dream for Celine to have a second child."

Dion, 41, and Angelil, 67, already have an eight-year-old son, Rene-Charles, who was also conceived using fertility treatments.

Angelil has three other children from two previous marriages.

There had been concerns that Angelil's bout with cancer and subsequent chemotherapy had rendered him incapable of having any more children.
