The singer-songwriter sparked speculation that she's tied the knot to her long-term partner Simon Konecki after she was seen with some sparkling new jewellery on her finger.
'Hello' singer Adele showed off two rings as she kicked off the first show of six nights at London's O2 Arena.
When contacted by Mail Online, her rep declined to comment.
There was a lot of romance in the air at Adele's concert on Tuesday night when a couple, Natalie and Johnny, got engaged as she performed 'Make You Feel My Love'.
Speaking to Mail Online, bride-to-be Natalie said: "I actually can't believe it. It's absolutely crazy what happened last night. I'm completely flabbergasted - I'm on cloud nine.
I'm on my way to work, just done the school run and everyone is sending me messages to congratulate me and say they've seen us on the news and on videos – it's unbelievable."
