Here comes the future Mrs. Pratt!
A source described the shower as "beautiful and elegant" and it featured a pretty star-studded guest list with Oprah Winfrey among the 100 attendees.
The source told E! News that the bride-to-be "looked stunning in a white skirt and fitted tank top with beaded fringe. Her hair was clipped back on one side." Schwarzenegger wore a Lela Rose "Dawson" dress from her bridal collection.
Guests arrived at Shriver's home around noon for a "backyard luncheon" that was described as "very traditional and exactly what you would imagine for a classic bride."
There was live music from a guitar player as well as lots of champagne. "There were photos of Katherine and Chris in picture frames at the entrance and large cherry blossom arrangements," the insider shared.
