Katherine Schwarzenegger's life as a married woman is off to an awesome start ... just ask her stepson, who's clearly enjoying it.
Chris Pratt, his son, Jack, and Katherine had an evening out in Pacific Palisades Tuesday, including a celebratory dinner at Blue Ribbon Sushi and a movie. Since Chris and Kat just tied the knot on Saturday ... this would be their first "official" family outing.
