The buzz around her highly-anticipated big screen release is reaching fever pitch, but last night it was Sarah Jessica Parker's incredibly veiny hands that were the talk of the town.

Sarah has previously attempted to downplay her daily exercise timetable claiming she's more inclined to "go to a dinner party than slave away in the gym".

But the former dancer is known for keeping to a tough daily exercise regime of running, climbing stairs, yoga and Pilates.

Still, Sarah appeared to be enjoying her night off, signing autographs for fans ahead of tonight's world premiere of Sex And The City in London.

Later she was joined by co-star Cynthia Nixon outside the Wolseley Hotel in Mayfair.

When pressed to give a hint about the plot line, SJP said: “ It's about forgiveness and pursuing love in a way that is real and meaningful”.

“I think it's about what it means to be a grown-up, and to recognise your own complicity and disappointment,” the BBC previously reported her as saying.

“I think in your 20s you spend a lot of time making the boys the villains.

“There's a difference when you're 40."

“You really experience loss and disappointment and you have to reconcile what part you played in it.”

The actresses are then set to return to the US for the New York premiere on May 27.
