Hayes is likely the last member to join the Alba-Warren brood. The Honest Company founder revealed to Extra back in November that after baby number 3, she was “done, done, done!”

She continued, “Yeah, my friend was like, ‘You are gonna have another,’ and I’m like, ‘No, I’m not … ‘ I just want a healthy baby … We’re good — three is good.”
