Kristin Davis by Gregg DeGuire/ Kristin Davis by Gregg DeGuire/

We expected this from Samantha, but little ol' Charlotte?! Trusty TMZ has gotten wind of a series of 20 still photos pulled from a circa-2003 sex tape purportedly starring Sex and the City good girl Kristin Davis and her ex-boyfriend. Granted, the resemblance is rather uncanny (or so my friends tell me... ), but apparently it's merely a look-alike. "This is not a photo of Kristin Davis," the actress' rep told TMZ when presented with one of the frame grabs. "There is no sex tape."

What do you think, those bold enough to click that above link (or even bolder to track down the actual explicit photos) - is it Kristin or her evil twin? - MWM
