The actress has previously spoken fondly of the chaos in their household. She told Shape: "I love my loud household with mayhem and the craziness and all the love and all the dirt. I love [parenting] with my husband. I love feeling like hugs and cuddles can make everything better. I love the pressure of being like, ‘How the f*** are we going to make it through this day?’
"And making it through the day and being like, ‘I don’t know how everyone is tucked in and fed and happy after all the things we’ve had to do today.’"
