Adele has married the comedian Alan Carr and his long-term partner in her back garden in Los Angeles.
She even "got ordained", enabling her to officiate.
After Carr revealed the news on a TV programme, the singer posted an image of herself in a long white dress, with the caption: "Seeing as the cats out the bag."
She added: "I married two of my best friends in January. You know me any excuse to dress up..."
Carr, 41, and party planner Paul Drayton have been together for about 10 years.
"She got ordained and she married us. She is the kindest and most sweetest," Carr told ITV's This Morning.
"She flew us to Vegas to see Celine Dion sing.
"She sang my first dance.
"It was the best day of my life."
In January, Carr's publicist said the couple had married in a "small, private ceremony", and were planning a bigger celebration for friends and family in the UK in the summer.
