Adele gave two gay fans the night of their lives on Tuesday when she helped them get engaged.

The 28-year-old singer invited André Söderberg and Simon Carlsson, who reportedly hail from Sweden, onstage during her May 3 concert at Denmark's Forum Copenhagen, E! Online reports. Apparently, the Grammy-winning superstar had selected the couple out of the audience for wearing quirky Flying Tiger eyewear and was surprised when Söderberg dropped to one knee and popped the question to Carlsson.

Video footage of the big moment was posted on Twitter.

After Carlsson accepted the proposal, Adele began jumping giddily.

“That’s amazing,” she said. “I’m going to cry!”

She even jokingly offered to help the pair start a family, telling them, "Should I be your surrogate if you have children? I'd love to have a baby with someone Swedish."

Söderberg later told reporters that the proposal was not pre-planned.

"I had been thinking about asking him to marry me but when Adele invited us to the stage, it just happened," he said. "I had a plastic ring on which we had bought earlier in the day when we were buying costumes, so I took that ring and put it on his finger. What can I say -- I just love him so much!”

“I get a lot of mail from people who tell me that I make them really happy to be themselves, and really comfortable with who they are, which I love,” she told Out magazine.

Congrats, gentlemen!
