Penn Badgley and his wife were on shaky ground before their family blossomed. The You star appeared on Monday's installment of the Totally Booked With Zibby podcast and opened up about his and wife Domino Kirke's struggle to welcome children together - a major point of contention in their relationship: "Especially for us, me at that point, not having any biological children, my wife having her firstborn ... that was a real inflection point." Before meeting in 2014 and going on to tie the knot in 2017, Domino welcomed her first child, a son named Cassius, with ex Morgan O'Kane.
