All About Chris Pratt's Fiancé Katherine Schwarzenegger's Bridal Shower

Chris Pratt has been in a whirlwind relationship following his separation from Anna Faris, and his new fiancé's bridal shower has already come and gone.

Katherine Schwarzenegger is the eldest daughter of Arnold Schwarzenegger and Maria Shriver. She and Pratt had their red carpet debut as a couple at the premiere of Avengers: Endgame, and the bridal shower was held this past Saturday. The party reportedly included a guest list of over 100 famous faces--such as Oprah Winfrey.

A source told E! News that Katherine "looked stunning in a white skirt and fitted tank top with beaded fringe. Her hair was clipped back on one side."

The "backyard luncheon" was held at Katherine's mother's home, and was described as, "very traditional and exactly what you would imagine for a classic bride." Following lunch, a source said that, "Some of Katherine's friends spoke, her sister said something and then Maria gave a very long tribute to Katherine with the theme that she was born to love and to be loved."

Pratt himself made an appearance around 2 p.m., and was met with cheers and whooping from the crowd. "Everyone commented that it was the most beautiful shower they had ever been to. Even Chris said it was incredible and only something you would see in the movies," the source concluded.

We're sure the couple's wedding will be just as beautiful!
