The 24-year-old singer honored the 22 killed and dozens more injured at an Ariana Grande concert at Manchester Arena last May during his concert at the same venue on Monday. Styles chose to perform "Just a Little Bit of Your Heart," a song he wrote and Grande recorded in 2014, while recognizing those affected by the attack.
"I grew up coming to my first concerts in this room. I love this room,” Styles said to the crowd. “The next song that we’re going to play for you I wrote a few years ago, and I gave it to a singer called Ariana Grande. She sang it a few times, and now we’re going to do our version of it for you."
"If you can find some way to join in please do so," he continued. "I stand with you, Manchester.”
This isn't the first time Styles has spoken out about the Manchester attack. The former One Direction member made a personal call to Freya Lewis, a 14-year-old fan who was injured in the bombing, while she was receiving intensive care at the Royal Manchester Children's Hospital last May.
