The songstress was belting out her anthem Make You Feel My Love at her London gig when she apparently spotted a proposal in the audience.
Channelling her inner Cupid, she stopped everything shouting, “Two people just got engaged!”
The 27-year-old then invited the newly-engaged duo to share the moment with their closest 20,000 friends at London’s 02 stadium.
Adele, being classic Adele, greeted them with huge hugs before laughing and telling them to just “get over” their stage fright.
The mum-of-one jokingly asked the couple how they managed to hear the proposal over her “wailing” and the pair explained that Make You Feel My Love was their song.
“You’ve been together longer than I’ve been making music!” she squealed after finding out the pair have been together for 12 years and have a son, Alfie.
“That was the most beautiful thing I’ve ever witnessed at one of my shows. Thank you.”
Marriage seemed to be on a lot fans’ minds after they noticed the multi-Grammy award winning musician was sporting what looked like a wedding band on that finger.
While she has been adamant that marriage is far from her mind, the gorgeous sparkling bands had onlookers wondering if Adele secretly tied the knot with her long-term partner Simon Konecki, who is the father of her three-year-old son Angelo.
“We just haven’t felt the need to get married,” she told Rolling Stone last year.
“We’ve got a kid together. I feel like that’s a big enough commitment.”
