The Clinton family celebrated an extra special Father's Day this year, thanks to the arrival of Chelsea's son, Aidan, on Saturday. Just one day later, the family shared the first pictures of the new arrival via social media.
"At 7:41 AM Saturday, our family and hearts expanded with Aidan's arrival. We are blessed," Chelsea, 36, tweeted on Sunday.
Aidan's famous grandparents, former President Bill Clinton and the presumptive Democratic presidential nominee Hillary Clinton, also shared photos on Twitter.
"What a joy being with our new grandson, Aidan. So grateful," Hillary captioned a photo of Aiden snuggled into her arms with her husband.

Bill shared a Father's Day photo with his grandson and son-in-law, writing "Aidan has made two dads very happy this Father's Day. Hillary and I are thrilled for Marc and Chelsea!"
Aidan is the second child for Chelsea and her husband, investment banker Marc Mezvinsky. Their first child, Charlotte, will turn two in September.

Hillary had her own Father's Day wishes for Bill, posting this adorably awkward throwback pic of them with a young Chelsea, holding hands with Donald Duck.
