Baby day! Us Weekly is reporting that Nicole Richie is currently in labor. Joel Madden was spotted on his way into the delivery area of Cedars-Sinai where Nicole already is. As if that's not exciting baby news enough, Christina Aguilera has apparently been at Cedars since last night. She was planning to have her baby through C-Section. How adorable will it be if both these new celebrity additions are born on the same day? We can't wait to hear more and we'll keep you updated! We hope everything goes smoothly with the deliveries and early congrats to the families.
