Shyly, one of the girls piped up and introduced herself to the Grammy Award-winning singer.
"I'm Daisy and this is my sister, Ruby!"'
After chatting back and forth, Adele leaned over and asked the girls where they're from - that's when they revealed they hail from England, just the songstress herself. Then a lightbulb went off in Adele's head!
She knew the little ladies for years! Shocked, Adele explained her connection to the girls.
"I knew you when you were a baby! Oh my God! Your mom plays for me - she plays cello. You were like two weeks old when I first met you!"
The girls are now beautiful young ladies, and they'll always have the memory of Adele recognizing them on stage.
Unfortunately, moments like this may be a thing of the past. In an emotional Instagram post, Adele explained that her life on tour may be over.
"Touring is a peculiar thing, it doesn't suit me particularly well. I'm a real homebody and I get so much joy in the small things.
Plus I'm dramatic and have a terrible history of touring... I only ever did this tour for you and to hopefully have an impact on you the way that some of my favourite artists have had on me live. And I wanted my final shows to be in London because I don't know if I'll ever tour again and so I want my last time to be at home."
Adele has been outspoken about her stage fright and dislike for performing in front of thousands of people. Thankfully, the girls got to meet their idol before she stops touring altogether!
