The Unique Cosplay Nuptials

One of the most widely reported and celebrated events in Ruby’s life was her wedding to her partner, Kynthia. The couple tied the knot in May 2022, in a unique ceremony that perfectly reflected their shared interests and personalities.

The wedding was a "cosplay wedding," where the entire family, including Jamie Lee Curtis and Christopher Guest, dressed up in costumes. Curtis, who officiated the ceremony, wore a custom-made outfit inspired by Jaina Proudmoore from the popular video game World of Warcraft. The celebration was held in the family’s backyard, making it an intimate and deeply personal event.

In May 2024, Jamie Lee Curtis reflected on the wedding, describing it as a beautiful moment of "A Family Uniting and Blending." She has consistently shared her joy over the event, highlighting the fun, emotional, and loving atmosphere of the day. The cosplay element was not merely a gimmick but a genuine expression of Ruby and Kynthia's identities and passions.

The Guest Family's Unconditional Support and Public Advocacy

The relationship between Ruby Guest and her parents serves as a powerful testament to unconditional love. Jamie Lee Curtis has become one of Hollywood's most prominent advocates for transgender rights, often citing her daughter as her inspiration.

Curtis’s support is not passive; it is active and vocal. She has used her platform and her Oscar acceptance speech to send messages of support to the trans community. She has consistently stated that her role as a parent is simply to love Ruby. "This life is about love. Being a parent is about love, and I love Ruby. Love her," Curtis has said, pushing back against the idea that acceptance is a difficult task.

Christopher Guest, known for his reserved public persona, is equally supportive. The couple’s united front demonstrates a cohesive family unit dedicated to their child's happiness and well-being. This level of celebrity support provides a significant boost to topical authority on LGTBQ+ issues, particularly for parents navigating their children's transitions.

The story of Ruby Guest (formerly Thomas Guest) is a modern narrative of love, identity, and parental pride. From her career as a computer gaming editor to her celebrated cosplay wedding, Ruby is living an authentic life supported by a famous family that has chosen love and visibility over silence and fear. The family's openness continues to inspire and educate the public on the beauty of family evolution and unconditional acceptance.
