(Cover) - EN Showbiz - Cline Dion says she is "open" to having more children.

The mom of three recently celebrated the first birthdays of her twin boys Eddy and Nelson, with her husband Ren Anglil.

The couple also have a ten-year-old son Rene-Charles.

Although Cline admits having twins has been stressful at times, she would consider expanding her brood in the future.

"Let's put it this way, it's not a closed conversation," she said in an interview with the British edition of Hello! magazine. "We're keeping it open but we don't have any plans, of course not. If we do [try again] we'll let you know! "Right now we're enjoying what we have and we're so proud. I can't believe the twins are already a year old. This year's been quite something. I don't know how I did it. But I would do it all over again."

Cline, 47, and 69-year-old Rene will celebrate their 17th wedding anniversary next month.

The singer is incredibly excited about a family holiday they have planned for the occasion.

"We're going to be doing our first ski trip. We're going with friends to Utah. The twins will be playing in the snow, I'll be making snow angels and RC will learn how to ski. It's going to be phenomenal. I just can't wait," she gushed. (C) Cover Media
