Ashlee Simpson may only be 24, but she's got one thing older sis Jess wants: a baby.
"She's always saying, 'Oh, I want a baby!' " Simpson tells October's Redbook, on sale Sept. 22. "Being a mom's so empowering and incredible. I'm one of those people who believes that life brings things to you at a certain time for a certain reason, and if you just go with it, that's where the best moments come from."
