Celine Dion and husband Rene Angelil are doubly joyful this weekend, welcoming fraternal twin boys who were delivered via C-section on Saturday morning in West Palm Beach, Fla., joining big brother Rene-Charles, age 9.

The babies have not yet been named, according to People.com. "Celine is resting now and they plan to discuss what to name the boys when she wakes up," her spokesperson says. "René-Charles has been to the hospital to visit his brothers, and is just so excited they are here."

Dion's new sons were born at 5 lbs., 10 oz., and 5 lbs., 4 oz., and are premature but healthy. They will reportedly spend a few days in neonatal intensive care, a common procedure for newborn twins, who often arrive before their due date.

At a press conference outside St. Mary's Medical Center, Dion's longtime obstetrician talked about the successful delivery -- and what the babies look like.
