Time flies!

Ashlee Simpson is now the mother of two, but back when she was 18, she poked fun at her older sister Jessica for her plans of being a mom.

"When I'm a mother, I want to actually be a mother. I don't want a nanny doing everything for me," Jessica told ET in December 2002.

Ashlee couldn't help but tease her sister, jokingly saying, "You got to get to cleaning your own stuff before you can clean your kids' stuff up too!"

It's safe to say that the two sisters have a lot of cleaning up to do now that they both have two children.

Jessica, 35, is mother to daughter Maxwell Drew, 3, and son Ace, 2, with husband Eric Johnson.

Ashlee and her husband, Evan Ross, announced they were expecting their first child together last December, months after they wed at his mother Diana Ross' Connecticut home. Ashlee has a 6-year-old son Bronx Mowgli, from her previous marriage to Fall Out Boy's Pete Wentz.
