Three or four years later she went to get the other one and it was an identical twin. It's called a laboratory twin. Technically it's called a twin. However, even if the embryo is implanted and carried to term, it could not be a twin of the child she is carrying. Identical twins are created from a single embryo that splits in the womb.
Fraternal twins come from different embryos that are carried at the same time.
Dion also said in the interview that a name has not been chosen for her son, but added that the name might include Rene. One year after beginning a sabbatical, Dion said she feels fulfilled to finally be doing something other than performing. She said she was exhausted and didn't feel like her heart was fully into her final performance at Montreal's Molson Centre last New Year's Eve. However she said she might record another album one year after her son is born. As part of an unprecedented alliance, Sony Music recording artist Celine Dion has accepted an offer to perform in an exclusive, extended engagement at Caesars Palace in Las Vegas.
