To mark Mother's Day on Sunday, the magazine chose 10 women who lead the way in their chosen careers. Jennifer Owens, Working Mother Media's Editorial Director, told UsMagazine.com, "(They) are just a few of the moms making a major impact right now. All of the power women on our list have at least one child 18 or younger, and all are based in the U.S."
Beyonce became a first-time mom in January when she welcomed daughter Blue Ivy with husband Jay-Z. Meanwhile, Angelina manages a brood of six children with her partner Brad Pitt.
Melissa McCarthy ("Bridesmaids" and "Mike & Molly") came in at number three on the list. She is the mother of two daughters - Vivian and Georgette.
Other notable moms on the list include "The Hunger Games" author Suzanne Collins and "Today" show co-host Ann Curry.
