Celine Dion's twins are already developing different personalities.

The 'Think Twice' singer - who gave birth to Eddy and Nelson on October 23 - and her husband Rene Angelil are in awe of their babies and think the infants are already developing their own identities.

Celine said: "They're so cute it's incredible. When we look at them we can't believe it. And to have them here at home - it's all we could wish for."

Rene added: "One is more gutsy than the other. Nelson seems to have a little stronger personality right now, he's the tougher of the two. Nelson weighed more at birth but the doctor told us in a week or two, they're going to be the same."

However, the couple - who also have a nine-year-old son Rene-Charles - said the twins are identical in expressing their needs.

Celine told Britain's Hello magazine: "When one cries the other cries, or they both don't cry."

Despite Rene thinking the babies look "very alike", his eldest son disagrees.

Rene said: "Rene-Charles came to the hospital right after his baseball game and he was thrilled. He said, 'One looks like Dad and the other looks like Mum.' "
