Lots of celebrities gave birth over the weekend, including actress Courtney Thorne-Smith and “In Living Color’s” David Allen Grier’s wife. Who and who? Exactly. Now, for the Hollywood pregnancies you were actually aware of:

First up — Nicole Richie. People magazine says

Nicole Richie and her rocker boyfriend Joel Madden are the parents of a daughter. Harlow Winter Kate Madden was born Friday at Cedars-Sinai Medical Center and weighed 6 lbs. 7 oz.

Christina Aguilera also pooped¹ one out over the weekend. People magazine says

Christina Aguilera and Jordan Bratman welcomed a baby boy on Saturday at 10:05 p.m. Max Liron Bratman [weighed] 6 lbs., 2 oz. and 20.5 inches [and] arrived late on Saturday night in L.A.

I’d bet that Max is gonna grow up to be a real looker, what with Dad’s imaginary chin and Mommy’s spackle-and-pancake complexion. He’d probably have just as much luck in the gene department with Amanda Lepore and Wimpy from Popeye for parents. On the plus side, ought to have a built-in role as a young Boy George in E!’s made for TV movie “Karma Chameleon:The Many Colors of George Alan O’Dowd.”
