In January, the couple shared the arrival of their baby girl on social media.

"Happy New Year from the Maddens!" Diaz and Madden began their announcement on Instagram. "We are so happy, blessed and grateful to begin this new decade by announcing the birth of our daughter, Raddix Madden. She has instantly captured our hearts and completed our family."

Madden recently sang his wife's praises in a sweet Mother's Day post, writing, "Whether waking up extra early to take care of everyone (3 humans and a dozen animals) or doing all the research and reading to make sure we try our best to be good parents for our daughter, she's a force of nature and I'm very grateful."
