Polly McCourt recently gave birth on a sidewalk in the Upper East Side of New York City.

According to Jezebel.com, McCourt and her doorman tried to hail a cab to the hospital yesterday afternoon.

"She was like, 'Oh, my God, the baby's coming'," one witness told Fox 5. "And then I could see the baby's head coming out."

Several bystanders stopped to help McCourt, including ladies who gave up their scarves and a coat for the baby.

Her husband, Cian, arrived in time to see the birth of his child on the sidewalk (video below).

McCourt was seen smiling as she was loaded into an ambulance with her newborn.

Polly and her baby girl are reportedly doing well at the Lenox Hill Hospital.

Polly and Cian named their daughter Lla Isabel after a female bystander who gave up her coat.
