Celine Dion is pregnant with twins.

The 'Think Twice' singer and her husband Rene Angelil - who already have nine-year-old son Rene-Charles together - are preparing to extend their brood after their sixth round of in-vitro fertilisation (IVF) was successful.

Celine is currently 14 weeks pregnant and the couple are expected to find out the se of their babies next month.

Rene told People.com: "We're ecstatic. Celine is just hoping for a healthy pregnancy. She was hoping for one baby and the news that we are having two is a double blessing!"

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 days 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."
