Samberg and Newsom married in 2013, after five years of dating. The musician opened up about having kids in a December 2015 interview with Larry King.
"Little harpist Samberg, thank you for putting that image in my head," she said, before gushing about her husband. "He’s my favorite person in the world. He’s the person I would most want to hang out with at any given moment. He’s probably the biggest superfan of my music."
"I love babies," Samberg told reporters at the Fox All-Star Party just one month later. "I would love a baby someday."
While Samberg and Newsom just welcomed a baby girl, Serena Williams and Alexis Ohanian just celebrated their baby shower. See their adorable '50s-themed soiree in the video below.
