Adele was taken aback during her concert on Wednesday, June 1, in Amsterdam when she brought two young fans onstage and then realized she knew one of the girls.

At first the “Hello” songstress thought she was meeting the girls for the first time but then realized that one of them was actually the daughter of her cello player.

Adele was in disbelief and uttered “Oh my God” several times and with excitement explained to the audience that she the met the child when she was just an infant.

“I knew her when she was a baby!” Adele exclaimed.
