The 'My Heart Will Go On' singer -- who gave birth to twin boys by Caesarean section on Saturday -- admitted while she would have loved to have given son Rene-Charles, 9, a sister but insists she "wasn't disappointed" to find out she was expecting a pair of boys after undergoing in vitro fertilisation (VF) therapy.

She explained: "Honestly if I had a choice, certainly I'd have liked to have a girl. But the day I learned that I was expecting two boys, I wasn't disappointed. It was a day of tremendous joy. I'm truly happy. Everything went well and the babies are in good health. That's all that counts.

"I'm telling you, if they could have come out through my ears at the time they were ready to come into the world, that would have suited me fine."

However, the 42-year-old star and her husband Rene Angelil are having difficulty deciding on names for the new arrivals.

Celine -- who is of French Canadian descent - added to France's Gala magazine: "I've read nearly 15,000 names and nothing has stuck.

"Because Rene-Charles goes to school in the United States, he's suggested English first names. My mother, on the other hand, has been hinting about very French first names and we're going a little bit crazy trying to decide."
