Canadian superstar singer Celine Dion is pregnant with her second child after undergoing fertility treatment at a clinic in New York, a newspaper reported on Tuesday.

The Journal de Montreal said Dion, 41, was due to give birth next May. Dion, who has made no secret of her wish to have another child, already has an eight-year-old son with husband Rene Angelil.

Dion’s official website carried no mention of the reported pregnancy. Montreal is the largest city in the predominantly French-speaking province of Quebec, where Dion was born.

She is one of the world’s top selling female singers and last year earned more than $235 million from her first world tour in eight years, according to trade publication Pollstar.

In 2003 she began a residency at Caesars Palace in Las Vegas, and grossed more than $385 million by the time the final show ended in December 2007.

The Journal de Montreal said Dion had been due to return to Las Vegas for another series of shows in late 2010.

Dion records with Song BMG, owned by Japan’s Sony Corp.
