Jamie Lee Curtis stepped into a new role on Sunday: wedding officiant.

Curtis' daughter, Ruby Guest, married her partner Kynthia on Sunday, as Curtis announced via Instagram.

"Wife is sweet," she captioned a photo of herself, Guest, and Kynthia, all of whom were in costumes.

Curtis, who recently starred in "Everything, Everywhere, All At Once," previously shared that Guest would be having a cosplay wedding in her backyard on an episode of "Jimmy Kimmel Live" in March.

"We're gonna have a beautiful picnic in the backyard," she told Kimmel. "I'm really excited."

"Both my children will have been married in my backyard, which brings me to tears," she added, referencing her other daughter Abby's wedding.

Curtis also shared that she would be officiating the wedding in a "World of Warcraft" ensemble she bought on Etsy during her Kimmel appearance.

Following the wedding, Curtis posted a second photo of Guest and Kynthia appearing to kiss at their wedding altar.

"Yes they do and they did," she captioned the shot. "Married!"

She posted one more photo from the event. In the shot, Curtis poses in a rainbow tunnel holding a knife.

"The ONLY thing left over at the end of this entire BEAUTIFUL wedding, after everything was taken away was this
f-ing BUTCHER KNIFE they cut the tiramisu wedding cake with," she wrote.

She wore a T-shirt that says "wife is sweet" in the shot, nodding to the first post she made from the event.
