Christina Aguilera and Nicole Richie | Back-to-Back Hollywood Celebrity Child Births

The stork was working overtime at Cedars-Sinai Medical Center this weekend, where Nicole Richie and Christina Aguilera gave birth to bouncing bundles of joy.

Richie and boyfriend Joel Madden welcomed daughter Harlow Winter Kate Madden, who weighed six pounds, seven ounces and has already gone home with her proud parents.

"The beautiful healthy baby girl left the hospital with her ecstatic parents," a rep for the couple told People.

Just a day after Harlow Winter Kate Madden entered the world, Christina Aguilera gave birth. Shortly after 10 p.m. on Saturday, the singer and her husband, Jordan Bratman, welcomed their first child, a son named Max Liron Bratman.

"He is a beautiful, healthy baby boy!" the couple's rep told People. "Mom is resting and doing well!"
