Chelsea Clinton and husband Marc Mezvinsky are the proud parents of a little girl.

Clinton, 34, confirmed the news on Twitter on Saturday morning and wrote, "Marc and I are full of love, awe and gratitude as we celebrate the birth of our daughter, Charlotte Clinton Mezvinsky."

The former first daughter and her hubby decided to wait until they were in the delivery room to find out the gender of their child, and she said in a recent interview, "There are so few mysteries in life -- any answer is a happy one. So my husband and I decided that we would enjoy this mystery for the nine-plus months that we're granted, and we are eager to find out what God will have given us."

Parents Bill and Hilary Clinton both re-tweeted their daughter's announcement.
