More pink for Kristen Bell and Dax Shepard: The couple welcomed their second daughter, daddy Dax tweeted earlier today. Delta Bell Shepard is here. She doesn't look like either @IMKristenBell or me, but we're gonna keep her anyway. #christmascameearly— dax shepard (@daxshepard1) December 20, 2014 Mama responded: The estrogen has now hit critical mass!
