Former president Bill Clinton and former secretary of state Hillary Rodham Clinton say they are “blessed, grateful, and so happy” to become grandparents.

Their daughter, Chelsea, gave birth Friday night to her first child, Charlotte.

Chelsea Clinton announced the news on Twitter and Facebook early Saturday, saying she and husband Marc Mezvinsky are “full of love, awe and gratitude as we celebrate the birth of our daughter, Charlotte Clinton Mezvinsky.”

The former president and first lady said Saturday in a statement: “Chelsea is well and glowing. Marc is bursting with pride. Charlotte’s life is off to a good start.”

The new parents live in New York City, but the family did not say where the child was born or provide additional details about her birth.

The news comes as Hillary Clinton deliberates whether to run for the White House in 2016. She is the leading Democratic contender to succeed President Obama, her 2008 campaign rival, and has said she expects to make a decision toward the beginning of next year.

She has called the prospect of becoming a grandmother her “most exciting title yet” and says she already 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.

Bill Clinton canceled a fundraising visit Saturday to Colorado for Democrats running for the Senate and governor, but he called in to an event for embattled Sen. Mark Udall to deliver his 11-minute speech by speakerphone.

“I hope I get an excused absence,” he told the crowd in Denver. “You all know my family just got a little bigger, and I figured I should stay home where I’m really needed.”

Even in her late stage of pregnancy, Chelsea Clinton, 34, helped preside over the family’s annual conference last week, conducting interviews onstage and announcing efforts to promote community service and to stop the killing of elephants and trafficking of ivory. An advocate for elephants, she warned that her child “could grow up in a planet without elephants.”

Chelsea Clinton grew up in the public eye as a teenager in the White House, later graduating from Stanford and Columbia universities. She worked in finance in New York and in public health, earning a doctorate from Oxford University.

She serves as vice chair of her family’s foundation, which was renamed the Bill, Hillary & Chelsea Clinton Foundation, and helps direct the organization’s humanitarian and philanthropic efforts around the globe. She recently departed NBC News, where she served as a special correspondent.

The new parents, who married in 2010, were friends as teenagers in Washington and both attended Stanford. Mezvinsky is a hedge fund manager and the son of former House members Marjorie Margolies (D-Pa.) and Edward Mezvinsky (D-Iowa), longtime friends of the Clintons.
