Adele dedicated a moving ballad "Make You Feel My Love" to victims of Brussels terrorist attack on the last night of her six-day show at London's O2 Arena.

Before she sang the song, she said, "This is 'Make You Feel My Love' and this is for Brussels tonight. I want you to all sing it with me alright so they hear us," and asked the audience to chime with her.

The audience lit lighters and cell phones, and followed heartily after the singer, after which thanked her fans for their participation saying, "I don't think I've ever actually been so moved before in my life at one of my shows. That was just so beautiful. Thank you very much for doing that ... I think they heard us."
