The new girl … is ALSO named Kristin.

… and goes by the name of Kristin Davis (spelled the same way) or Kristin Billie Davis.

(I don’t know about you, but I’ve had enough of Kristins to last me til December).

And what did Kristin Billie Davis get arrested for Tuesday? Allegedly charging for Sex in the City in New York. But her entertainment brought her reportedly $2 million a year!

Cra-zy.

Want to see what the bust … is all about? We have the picture for you.

Says the Post exclusively: “The ex-governor regularly patronized Wicked Models, the Manhattan-based operation taken down Tuesday, according to financial documents and other evidence unearthed in a yearlong prostitution in vestigation, law-enforcement sources said…. The revelation comes three weeks after Spitzer was outed as “Client-9″ in a separate federal hooker probe involving the New Jersey-based Emperors Club VIP. At the center of the new ring is Kristin “Billie” Davis, a busty bottle blonde who hails from a ough-and-tumble California trailer park. She has a reputation for hard-partying, shameless self-promotion and a rumored 10,000-name-long client list.”
