Ashlee Simpson said big sis Jess wants a baby of her own.
"She's always saying, 'Oh, I want a baby!" Simpson said of her sister in the October issue of Redbook.
"Being a mom's so empowering and incredible," the new mom gushed. "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."
The 24-year-old mom said she's calmed down a lot since she had her son, Bronx, and that she doesn't envy the single life of her songstress sister, according to excerpts of the interview first reported on by People.
"I've grown up so much," she said. "Your body is changing, and it's such an amazing time to feel that connection. ... Being pregnany was the healthiest I've ever been in my life. Except for the cupcakes."
