Special experience: Billie Eilish gave her fans a one-of-a-kind acoustic concert during her stop in Mexico City on Wednesday evening

‘I thought, if it was okay…if you’re down with me and Finneas singing five acoustic songs or something,’ she said.

The Bad Guy singer then remarked that, although it would not be safe for a full show to occur, she wanted to show her appreciation for her Mexican fans.

‘It’s not a show, I can’t do a show. Nothing is working and they won’t let me, it’s not safe for me, it’s not safe for you, but I have to give you something. So I’m just going to sing a couple songs,’ she said.
