Jamie Lee Curtis shared that her 25-year-old daughter with acclaimed director Christopher Guest is transgender.

With their daughter's permission, Curtis made the revelation in an interview with AARP magazine.

"We have watched in wonder and pride as our son became our daughter Ruby," the "Halloween" series star said. "And she and her fiancé will get married next year at a wedding that I will officiate."

The article mentions that Ruby works as a gaming editor. Married since 1984, Curtis and the "Best in Show" director and "This Is Spinal Tap" veteran also have a 34-year-old daughter, Annie, who's a married dance instructor.

Curtis says she and Guest have no grandchildren at the moment, but added, "I do hope to."

The interview with AARP reveals the "constant metamorphosis" in the 62-year-old "Knives Out" star's life, detailing her recovery from Vicodin and alcohol addiction in 1999. Curtis said that had she not straightened out when she did, she would have been "dead for sure."

Sober ever since, Curtis is enthusiastic about the future, and sees herself as "just a sober person — flawed, contradictory, broken and redeemed."

"I wake up every day at 4 a.m. and have so much on my mind," she said. "I'm just so crazy excited and creative right now. And I don't want to squander any of it."
