It’s official: Katherine Schwarzenegger and Chris Pratt are on their way to the altar. The couple will tie the knot next winter, but have already kicked off the pre-wedding festivities with a bridal shower held at Katherine’s mother Maria Shriver’s home in Los Angeles on Monday.

The 29-year-old author dropped a few hints on her wedding day style, as she wowed in a white dress from Lela Rose’s Spring 2019 Bridal collection. The body-skimming design featured a quilted lace pattern and tiered accents, and Schwarzenegger accessorized with a pearl-encrusted hair clip for added shine. 

Not that the occasion was lacking in star wattage, as the intimate gathering also included A-listers like Oprah and, of course, dad Arnold Schwarzenegger. Among the shower’s activities were wedding-themed games and a flower station where guests could make their own arrangements. A gospel choir provided the big finish—but not before the groom swung by to make a sweet toast in honor of his stylish bride-to-be.
