Chelsea Clinton's baby girl 'off to good start'
Former US President Bill Clinton and former Secretary of State Hillary Clinton said they are "blessed, grateful, and so happy" to become grandparents.
Their daughter, Chelsea (34), gave birth on Friday to her first child, Charlotte.
Chelsea Clinton announced the news on Twitter and Facebook, saying she and husband Marc Mezvinsky are "full of love, awe and gratitude as we celebrate the birth of our daughter, Charlotte Clinton Mezvinsky".
"Chelsea is well and glowing. Marc is bursting with pride. Charlotte's life is off to a good start," the former president and first lady said.
The Mezvinskys live in New York City, but the family did not say where the child was born or provide other details of the birth.
The baby has been eagerly anticipated as Hillary Clinton considers her political future.
She has called the prospect of becoming a grandmother her "most exciting title yet". She even has picked out the first book she intends to read to her grandchild, the classic Goodnight Moon.
She has said she didn't want to make any decisions about another campaign until the baby's arrival, pointing to her interest in enjoying becoming a grandmother for the first time.
Even in her late stage of pregnancy, the younger Clinton helped preside over the family's annual conference last week, conducting interviews on stage and announcing efforts to promote community service and stop the killing of elephants and trafficking of ivory.
An advocate for elephants, she warned her child "could grow up in a planet without elephants".
