Adele invites young fan on stage, realises she knows her, freaks out

Wrong. Because it turns out the 28-year-old London-born star actually knew one of them – although it took a while for the penny to drop...

"Oh my god, no way! I knew you when you were a baby!" Adele cried, when she eventually realised that the little girl is the daughter of her cello player. "You were like two weeks old when I met you."

This was followed by many more 'Oh my god's. It's possibly the most Adele reaction ever.

Clearly she's still struggling to conceal her surprise...
