Sarah Jessica Parker is reprising her role as Carrie Bradshaw for the big-screen version of “Sex and the City,” but “Extra” spotted the fashionista looking drastically different this week on the New York set.

One day she’s blonde and the next she’s brunette. “Extra” also noticed that Kristin Davis, playing Charlotte, was very pregnant one day on set – and not showing the next!

Are the characters going through some major transformations, or have producers tricked us all?

Bed Widdicombe, columnist for the New York Daily News, told “Extra,” “I’m hearing that the ‘Sex and the City’ producers are filming out of sequence and might be staging fake scenes around the city to keep fans guessing about the plot.”

He added, “Also, despite rumors of diva disagreements, all of the stars are getting along – so far.”
