SJP's Big Baby Delivery!

Their twins by a surrogate aren't due until this summer, but it seems Sarah Jessica Parker and Matthew Broderick are already stocking up on the essentials... and it looks like they're having girls!

Three huge bins (two pink, one white) of all kinds of baby clothes – dresses, onesies, blankets – labeled "Girls 0-6 months," were delivered to SJP's house in NYC today while she and son James Wilkie were at home with the nanny, an eyewitness tells OK!.

Matthew was out at work at his Broadway play, The Philanthropist. James stayed home from school today, as he had a pal leaving after a playdate once the clothes were delivered.
