Canadian popstar Celine Dion is expecting her second child.

According to spokesman Murielle Blondeau, the My Heart Will Go on hitmaker came to know about her pregnancy on Monday.

"We can confirm she is pregnant," the Telegraph quoted Blondeau as telling US Magazine.

She added that the singer and her husband René Angélil are "very happy".

Dion had undergone a fertility treatment in New York. The baby is due in May.

Dion's first child, René-Charles, 8, was also conceived by in vitro fertilisation at the same New York clinic eight years ago.
