It's the third child for the supermodel and her husband, Matthew Vaughn. Their son Caspar is 7, and daughter Clementine is 5.
No name has been announced, but I wonder if it will begin with a "C" as well?
The family released a statement that said mother and baby "are doing well".
Congratulations to the family! I can't wait to see this little girl, who I'm sure will be stunning.
