Kirsten confirmed the news Friday afternoon in an Instagram post that partially showed the newborn.
"Our sweet baby girl, Marli, is here," the caption read.
The couple, who tied the knot back in March, had their first child together, Kensli, in 2015.
Less than two years after entering parenthood, Chance spoke to Complex about his new role as a father and how it changed his perspective.
"I'm in a position where I want to be closer to my parents now because I realize how important that is," he said in his 2017 cover story. "There was never a point in my life where I could ever remember loving somebody as much or more than my mom until I met my daughter, and so it made me understand — my mom loves me more than she loves anybody in the world, and that's crazy to me."
He continued: "... It opened my eyes to understanding, like, the other side of death. I knew people that had kids; a lot of my friends had kids when they were young. But I had never experienced joy like that before."
