Chriss Pratt and Katherine Schwarzenegger got married Saturday at the San Ysidro Ranch in Montecito, California.

There’s no word on any celebrity guests yet, other than Katherine’s parents Arnold Schwarzenegger and Maria Shriver…and Pratt’s 7-year-old son Jack.

Rob Lowe was probably there too, since the rehearsal was held at his house . . . and he went golfing with Chris before the wedding.

Chris and Katherine both posted the same official wedding photo, and the same caption:  “We became husband and wife in front of God, our families and those we love.  It was intimate, moving and emotional.

“We feel so blessed to begin this new chapter of our lives.”

Chris is 39, Katherine is 29.  (Check out some pics here.)
