Davis, who played Charlotte on the HBO series and the two subsequent movies, adopted daughter Gemma Rose Davis over the summer. (Fun fact: Rose is the name of Charlotte and Harry's other child on SATC.)
"This is something I have wanted for a very long time," Davis told the magazine. "Having this wish come true is even more gratifying than I ever had imagined. I feel so blessed."
Davis can next be seen in Journey 2: The Mysterious Island, the sequel to 2008's Journey to the Center of the Earth.
