Our first look at Chelsea Clinton's newborn son, Aidan Clinton Mezvinsky, is here! The 36-year-old daughter of President Bill Clinton and democratic presidential hopeful Hillary Clinton gave birth to her and her husband Marc Mezvinsky's second child on Saturday, June 18. All three Clintons took to social media on Sunday to welcome the little guy to the family with new photos.

"At 7:41 AM Saturday, our family and hearts expanded with Aidan's arrival. We are blessed." Chelsea wrote on Twitter alongside a photo of her and Mezvinsky holding Aidan in the hospital.

Meanwhile, dad Bill was thrilled to celebrate his new grandson on Father's Day. "Aidan has made two dads very happy this Father's Day," he wrote on Twitter with a photo of himself and Mezvinsky holding the too-cute newborn. "Hillary and I are thrilled for Marc and Chelsea!"

Presumptive Democratic presidential nominee Hillary also chimed in. "What a joy being with our new grandson, Aidan. So grateful," she tweeted, alongside a sweet photo of her and Bill cuddling their new grandson.

Chelsea is already a mom to daughter Charlotte, who turns 2 in September. "I think my love for Charlotte has just opened more space in my heart and my brain that I didn't even know was there," she told People in last fall.
