Jennifer Lopez: Being a Parent Means Constant Worrying

Click through to see what the star-studded cast tells Redbook in the June issue, about the right time to have a baby -- and why some of them are holding off on taking that big step for the moment.

REDBOOK: Did any of you -- or do any of you -- have a time line in terms of when you thought you'd be married and have kids?

CAMERON DIAZ: I thought I was going to be married and have two children by the time I was 21. I think I felt I had to model my life after my mother's. But then my career was starting to take off, and there were still so many things I wanted to do. So that dream for me was shattered early on. After that, I never put another time-line on anything in my life.

BROOKLYN DECKER: I think whatever happens happens. It's funny, because when I think I want a baby, everyone tells me to live my life, enjoy my career and marriage for a while. My mom worked as a nurse when I was growing up, and it's a good example for kids to see their mom work. But right now, I'm going to wait a bit.

ANNA KENDRICK: I have no clue. It's not even something I think about. I just turned 26. Having a child is not on the agenda. I can barely take care of myself!
