Charlotte is obviously expecting a very big event

Plot details from the new Sex And The City movie have been kept under wraps but on-set photos reveal Charlotte York’s a big momma.

Kristen Davis, 42, who plays the prim socialite, has been snapped on the streets of New York looking extremely pregnant and rowing with Mr Big, played by Chris Noth.

In the TV series, Charlotte had struggled to conceive and had resigned herself to not having kids, settling for a family of dogs instead.

But now Kristen’s padding makes her look fit to burst – with twins at the very least.

Why is she arguing with Carrie’s boyfriend, though?

She was reportedly heard telling Mr Big, ‘I wish you were never born.’

Mmmm, wonder what he’s done now…
