The 56-year-old actress marked the "milestone" as her 18-year-old son James graduated from high school this week and she admitted she was very "weepy".

Taking to Instagram, she wrote: "Into the sunset of his High School career. Field day. The period at the end of a long sentence. And all the sunrises and sunsets in his future ...

"It's a milestone. Not fully understood til it's on your doorstep. And til they cross the threshold into their next mostly mysterious chapter. Just like all the other chapters that are part of the epic novel that is the story of child and parent. We, all of us Parker-Brodericks are proud, weepy and so looking forward to celebrating your coming graduation. Enjoy this beautiful day, you have earned it. (sic)"

Meanwhile, Sarah is gearing up for the 'Sex and the City' spin-off, 'And Just Like That...', and she previously revealed that seeing New York City in lockdown got her thinking about how Carrie, as well as Miranda Hobbes (Cynthia Nixon) and Charlotte York Goldenblatt (Kristin Davis) would be getting on.

Speaking recently, she said: "New York shut down in a way that also affects lots of other people because it's the centre of finance, it's the centre of culture, one could argue, and its silence was deafening. [Then I asked myself], 'Where are these women? Where are they?

"Can they find one another? Can they be together? What is their life like?' All these conversations were becoming a huge part of our experience inside of our homes, Michael and I just became really interested. And thus was born - 'And Just Like That.'"
