New parents Bill and Giuliana Rancic are so thankful for their little miracle baby Edward!
But until now, we didn't know to whom they were thankful.
The couple had been keeping the identity of their surrogate mother a secret, but now the secret's out.
Ch-ch-check out the video (above) to hear all about topless bonding, cutting cords, and what was too private for the surrogate to share!
It's kind of like watching the delivery dress rehearsal!
