Looks like congrats are in order for Chelsea Clinton! The former first daughter announced on social media Monday, July 22, that she had given birth to her third child with husband Marc Mezvinsky.

“This morning we welcomed our son, Jasper Clinton Mezvinsky,” the 39-year-old tweeted at 10:34 a.m. to let the world know the little guy had arrived. “We are overflowing with love and gratitude and can’t wait to introduce him to his big sister and brother.”

Mom Hillary Clinton couldn’t contain her excitement and took to Twitter to gush about the newborn too. “Sharing some happy news this morning! Bill and I are so thrilled.” We have yet to hear from dad Bill Clinton but we suspect the former U.S. president is enjoying some quality time with the family right now.

Chelsea and Marc, 41, are already parents to 4-year-old daughter Charlotte Clinton Mezvinsky, born in September 2014, and 3-year-old son Aidan Clinton Mezvinsky, born in June 2016. The Don’t Let Them Disappear author and the investor tied the knot back on July 31, 2010, in Rhinebeck, New York.

The couple announced that they were expecting baby No. 3 back in January when Chelsea took to social media and revealed the joyous update. “Marc and I have loved watching Charlotte be such a wonderful big sister and we’re excited to watch Aidan become a big brother!” she wrote at the time. “We cannot wait to meet our newest addition this summer.”

While she is happy playing the role of mom — in addition to numerous other important titles — these days, Chelsea revealed last year that a run for public office could be in her future.

“For me it’s a definite no now but it’s a definite maybe in the future,” Chelsea said at the Edinburgh International Book Festival in August 2018, “because who knows what the future is going to bring?”

Much love to Chelsea, Marc, Charlotte and Aidan as they enjoy their time with Jasper!
