Josh Madden (brother of Joel) may have said that Nicole Richie would be baby poppin' this week, but it was a total fake out: Nic gave birth to 6 lbs., 7 oz. daughter named Harlow Winter Kate Madden on Friday.

And after false reports that Christina Aguilera was in labor at the same time and hospital as Nicole must have sent the singer into contractions! Christina gave birth to her first child with hubby Jordan Bratman on Saturday, a son named Max Liron Bratman, who weighed 6 lbs., 2 oz.

We haven't had this much baby fever since Angelina Jolie and Gwen Stefani had Shiloh Nouvel Jolie-Pitt and Kingston James McGregor Rossdale a day apart in May 2006.
