(Cover) - EN Showbiz - Cline Dion and her husband Ren Angelil burst into tears when their twins were born on Saturday.

The 42-year-old singer delivered two boys weighing 5lbs. 10oz. and 5lbs. 4oz. respectively. The couple already have nine-year-old son Ren-Charles together and suffered many setbacks while trying to have another baby, with the new arrivals conceived during their sixth in-vitro fertilisation (IVF) attempt.

Ren, 68, has now opened up about the birth, saying neither he nor Cline can believe the twins are finally here. We have tried five times since March 2009 to conceive. It's very hard. So when Saturday at 11:11 came, and they showed us the first baby that was crying, we were crying, he said in an interview with Canadian television programme etalk. It was a very emotional moment and even though we didn't speak to each other, we were both thinking about the time it took. We are very lucky, very privileged and very fortunate to have these boys."

The proud father revealed at the moment the babies look very similar, but he expects their appearances to alter in the coming months as they arent identical.

Ren-Charles is also thrilled about becoming a big brother, and cant wait for his siblings to be old enough to play with him. His father explained he thinks his brothers look different, and has said one takes after mom and one dad.

He was very, very happy that it was boys, Ren laughed. I remember a few months ago when his mom told him the day we would find out the sex of the babies, his reaction pointing to his moms belly was 'I hope there's not too many girls in there.

Cline and her husband havent released the babies names yet. (C) Cover Media
