(CNN) - Chelsea Clinton announced Thursday that she is expecting her first child.
The only daughter of former President Bill Clinton and former secretary of state Hillary Clinton made the announcement while sharing the stage with her mother at a women's event in New York.
"Marc and I are very excited that we have our first child arriving later this year," Chelsea said at the end of the event.
"And I certainly feel all the better whether it's girl or a boy that she or he will grow up in a world full of so many strong, young female leaders. So thank you for inspiring me and thank you for inspiring future generations."
Clinton added: "I just hope I will be as good a mom to my child and hopefully children as my mom was to me."
Clinton married Marc Mezvinsky in 2010.
While a spokesperson for Clinton and Mezvinsky declined to answers questions about the due date, how long the couple knew about the pregnancy and why they chose to make the announcement at this event, they did say the baby is coming in the fall.
"Chelsea and Marc are very excited to be expecting their first child in the fall," the spokesperson said. "They have been blessed with incredibly supportive, loving families and can't wait to be parents themselves."
In an October interview with Glamour, Clinton said the couple wants "to start a family."
"So we decided we were going to make 2014 the Year of the Baby," Clinton said.
Equally important to the plan, she told the reporter: "Call my mother and tell her that. She asks us about it every single day."
Clinton talked about her mother's impatience for grandchildren in a 2012 Vogue interview, saying they were thinking about starting a family in "a couple of years."
Bill Clinton congratulated his daughter on the announcement, and he and his wife celebrated their new titles.
Jenna Bush Hager, the daughter of former President George W. Bush and Laura Bush, who gave birth to a baby girl last April, welcomed Clinton to the world of motherhood on twitter.
