Sarah Jessica Parker's surrogate has given birth to twins.
It's thought the couple were with the woman when she gave birth.
They already have a six-year-old son, James Wilkie.
Sarah and Matthew announced they were expecting twin daughters via a surrogate in April after they struggled to conceive naturally.
The 44-year-old actress then said: "We didn't expect it. I think after a certain amount of time, you tend to hold your hopes at bay a bit so as not to be disappointed. One really would have been thrilling and we would've felt incredibly lucky. And two was a comedy!
"James is really excited. He's very much ready to be an older brother. I think it gives him a great sense of pride. It's wonderful and I just hope for their safe arrival."
