Kristin Davis was spotted wearing a prosthetic baby bump on the set of the new Sex and the City movie yesterday, sparking rumours that her character Charlotte will be pregnant in the big screen version of the hit TV series.

In a scene witnessed by fans at the New York set, Charlotte was seen storming out of an Italian restaurant looking heavily pregnant. Chris Noth's character Mr Big then ran out after Charlotte, who was heard shouting back: "I don't want to see you. I curse the day you were born."

Onlookers claimed Charlotte looked like she went into labour before being driven away in Mr Big's car.

Davis' character was planning to adopt a child at the end of the TV series after she unsuccessfully tried to have a baby on numerous occasions throughout the show.
