After raking up over $415 million worldwide, you knew they'd have to go back to the well right?   Thankfully, after many months of conjecturing (and praying from fans), it appears a sequel is now officially on the books for the "Sex and the City" crew.  Well, at least according to a source of E!Online's Marc Malkin.  The columnist reports all four of the franchise's leading ladies, Sarah Jessica Parker, Kim Cattrall, Kristin Davis and Cynthia Nixon, have signed their deals for a new movie.

Of course, writer, director and original series producer Michael Patrick King hasn't written a script yet, but the film is still somehow expected to go into production this summer (less time for any pesky rewrites or studios notes!).

The triple threat has recently gone on the record saying the second "Sex and the City" film will be less dramatic than the first picture which centered on an almost year-long mourning period for Carrie (Parker) after her one true love, Big (Chris North), ditched her at the altar.  The big screen version of the popular TV series seemingly wrapped up all the loose ends in the franchise, with Samantha (Cattrall) back on the prowl anything is possible right? 

While the big names are all expected back (paycheck!) unclear is whether a new addition to the feature film's ensemble, Jennifer Hudson, will return.  Based on her current publicly announced schedule, it would be her first acting gig since the tragic death of her mother, brother and nephew last fall.

As for their post-"Sex" lives, Parker has not returned to the screen since "Sex's" stunning success last year.  Nixon recently appeared in "Lymelife," which debuted at this year's Sundance Film Festival," and just completed the indie drama "An Englishman in New York."  Davis appears in the upcoming Vince Vaughn ensemble comedy "Couples Retreat" and Cattrall has wrapped on "Miss January" (where she is rumored to play a former porn star) and is expected to join the ensemble cast of Roman Polanski's new thriller "The Ghost."

If all goes according to plan, the "Sex and the City" sequel should hit theaters in the Summer of 2010.
