Jamie took to Instagram to share a photo from the event and couldn't help but gush about her daughters.
"My family. Proudest mother. Loving support," Jamie wrote.
Ruby also later attended Jamie's hand and footprint ceremony — where she was also joined by her wife, Kynthia.
Since Ruby came out, Jamie has been open about her daughter's journey, watching in "wonder and pride" as she shared her true self with the world.
"I am here to support Ruby. That is my job. Just as it is to care and love and support her older sister Annie in her journeys," Jamie shared at the time. "I'm a grateful student. I'm learning so much from Ruby. The conversation is ongoing."
Jamie also said she and her daughter hope that if one person sees a photo of them together and says, "I feel free to say this is who I am," then it's all worth it.
It's wonderful to see Jamie is so supportive of Ruby! Check out our exclusive interview with Jamie here.
