Celine Dion pregnant with twin boys

Canadian singer Celine Dion is 20 weeks pregnant with twin boys, she announced on her website on Friday.

The 42-year-old entertainer's husband-manager Rene Angelil, 68, is the father.

"Celine and Rene Expecting Twin Boys!" said Dion's website. "Celine first announced the upcoming new additions to the Angelil-Dion family back in May, and now she just revealed that she is expecting twin boys!"

The pregnancy was the result of Dion's sixth in-vitro fertilization attempt, according to reports.

Dion turned to acupuncture therapy to improve her chances of getting pregnant.

The couple already has a nine-year-old son, Rene-Charles.

Dion, a five-time Grammy winner, is expected to return to Las Vegas, Nevada, next March to begin a three-year residency at The Colosseum at Caesars Palace.
