Jennifer Lopez says pregnancy has helped her "evolve".
The 38-year-old singer - who is due to give birth to twins later this month - admits the prospect of motherhood has forced to her "grow up".
Jennifer - who is married to singer Marc Anthony - said: "I am at the beginning of a huge change. I think everyone is constantly changing and evolving, new things are becoming important in our lives all the time - and never more so than for me now.
"The whole growing up thing, maturing - its' difficult but everyone has to do it."
This week Jennifer's father confirmed his daughter is expecting twins. David Lopez said: "It's, twins. The thing is, in my family, my sister also had twins, so it's a hereditary thing.
"I'm very proud. Jennifer has yearned to be a mother for many years."
David, who comes from Puerto Rico, has already bought traditional gifts for his unborn grandchildren.
He said: "In Puerto Rico it's custom to buy an azabache (black stone) bracelet for babies to protect them from the evil eye, it's part of our culture."
Jennifer sparked rumours she was expecting twins by purchasing matching pink and blue romper suits embroidered with the words "prince" and "princess".
It was recently revealed Jennifer and Marc are planning to call their unborn twins Max and Emme, after J.Lo's mother Guadalupe was seen buying engraved gold bracelets in New York.
A source said: "The day before J.Lo's baby shower, Guadalupe picked up two gold-rope baby ID bracelets engraved with the names Max and Emme from a jewellers in New York."
