I remember when @kourtneykardash was pregnant with Reign and it started to get close to Mason’s bday I suggested she induce so that they don’t have the same birthday but she said her famous phrase “whatever’s meant to be will be”. And her water broke the night before Mason’s bday and little Reign was born on Mason’s day! Happy Birthday to the coolest boys in the world!!!!」12月15日 9時56分
