(Cover) - EN Showbiz - Sofia Coppola admits the sister bond between her daughters is mysterious to her.

The celebrated director was raised in a household surrounded by all boys including two older brothers and various male cousins. As a result, Sofia admits she has always felt able to relate easier to men as opposed to women as she is used to being the only girl in a male dominated environment. The star admits that her experiences will differ greatly from her daughters, Romy,4 and Cosima, 7 months, who will undergo something she never had.

The idea of sisters is mysterious to me, some kind of complicated relationship that I dont know about. I hope theyre close. At first Romy was annoyed [about Cosima's arrival], but now shes really into being a big sister, she told People magazine.

In addition Sofia concedes that her life has changed dramatically since her second child. The Lost in Translation director reveals she has successfully managed to combine work and family life.

I cant stay up all night writing anymore. I have to be more organized and it takes longer to write in all the chaos. I once had this idea that I needed to be in a quiet room to write, but Ive learned to do it with kids running around, she added (C) Cover Media
