Ariana Grande Manchester Concert Backstage Footage Goes Online

(Radio.com) Ariana Grande's One Love Manchester concert assembled a pantheon of superstars on short notice to lift the spirits of a city stricken by terror. Katy Perry was one of the first performers announced for the gig and jetted to the UK to honor victims of the May 22 concert bombing--wearing a dress adorned with their faces.

Now Perry has shared behind-the-scenes footage from backstage at the concert. Viewers can watch her chit-chat with Miley Cyrus and greet Justin Bieber with a hug. 'It's awesome that you're here, doing this," she told him.

During an early rehearsal, Perry gave Ariana an extended hug--and passed Chris Martin in a hallway. The video culminates with Perry's performance of "Part of Me" during the main event. Watch the touching video here.
