Madden and Diaz wed in January 2015 and welcomed their first child in December 2019. "For years, Cameron wanted to be a mom," a source told PEOPLE last June. "She loves it more than she imagined. They are the perfect team and love being parents."

And last July, the Avaline co-founder raved about motherhood, when she appeared on The Tonight Show Starring Jimmy Fallon. "Literally every single day, there's just leaps and bounds ... and she's not the same baby that she was yesterday," she said.

"Where was yesterday?" Diaz continued. "Yesterday is literally gone, and today is a new day, and tomorrow will be a new day that she's a completely different baby."
