The couple tied the knot in Montecito, California after a little more than a year of dating. Katherine's famous family — mom Maria Shriver, dad Arnold Schwarzenegger, and brother Patrick Schwarzenegger — were all in attendance.
Schwarzenner and Pratt announced their engagement in April when he shared the happy news on Instagram, writing, “Sweet Katherine, so happy you said yes! I’m thrilled to be marrying you. Proud to live boldly in faith with you. Here we go! ??.”
