The 'Think Twice' singer – who already has a nine-year-old son Rene-Charles with husband Rene Angelil – has confirmed she will be welcoming two more sons into her family later this year.
In a statement on her website, he spokesman said: "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! Congratulations to the happy family!"
The 42-year-old songstress has had an emotional few months as she tried to have more children with her 68-year-old spouse.
Last August the couple announced they were expecting a child following a successful round of IVF, but in November her spokesperson confirmed the pregnancy had failed.
Just weeks ago Celine hinted there was some "good news" to come about a second pregnancy.
She said: "Well we're crossing our fingers. We're waiting for good news hopefully. I don't want to talk about it so much because I'm superstitious, but I know people have been very wonderful for us and praying for us. Right now we are crossing our fingers, we hope for the best and I can't wait to give people good news."
The French-Canadian star deliberately didn't want to release information about her bump until she was sure she was pregnant.
She added: "Once you live in showbusiness and everything spreads out so quick and every pregnancy you have to wait three months to make sure it's all ok and it's nerve racking. We're not getting any younger and you always think it's your last chance, you're last try."
