The couple said "I do" in a romantic ceremony at the San Ysidro Ranch, a high-end 500-acre resort, on Saturday, June 8.
According to reports, the actor, 39, and the 29-year-old daughter of Arnold Schwarzenegger and Maria Shriver held a rehearsal dinner the night before the nuptials at family friend Rob Lowe's nearby estate.
The pair began dating in June 2018, a year after his split from first wife Anna Faris. Pratt and Faris share a 6-year-old son, Jack.
This is the first wedding for Schwarzenegger, who has often been spotted doting on her new stepson.
