Celine Dion welcomed fraternal twin boys Saturday in West Palm Beach, Fla., her rep tellsUsMagazine.com.

In a statement, Dr. Ronald Ackerman, Dion's obstetrician and gynecologist, told Us: As coach and confidant for over 12 years for Celine and Rene, it is an honor and privilege to make this announcement on behalf of the Celine and Rene. At St. Marys Medical Center, at 11:11 and 11:12am, Celine gave birth to 2 healthy baby boys weighing 5lbs 10 ounces and 5 pounds 4 ounces. The cesarian section was performed by the team and Dr. Ruel Stoessel, Celines obstetrician, and high risk doctor and obstetricians Dr. Steven Pliskow and Dr. Joshua Ackerman, my son. I would like to thank Dr. Stoessel, Celines high risk obstetrician who availed his high level of expertise to enable us to reach this joyous day. I would also like to thank Dr. Zev Rosenwaks for his tireless fertility treatments which afforded Celine and Rene with this opportunity, and to Dr. Pete Garcia, our pediatric physician who played an enormous role in her care. It should be known worldwide that this team agrees that Celine and Rene are clearly one of the most caring and kind individuals that they have ever cared for. Today is not the end, but the beginning of 2 new lives.

Still no word on the babies' names.

Dion announced in May that she was pregnant after undergoing her sixth in-vitro fertilization attempt.

"We believed in trying one more time," she told French magazine Paris Match this summer. "If [the doctor] had told me that my body was too tired, I would have given up."

She has a son, Rene-Charles, 9, with her husband/manager, Rene Angelil.

"We'll do the same thing we did with Ren-Charles, who stayed with us in our bedroom for the first year," Dion told Paris Match of her twins. "We'll keep them near us, too, because we have a big bed."
