After postponing several of his Justice World Tour shows due to his Ramsay Hunt syndrome diagnosis, the singer returned to the stage at the Lucca Summer Festival in Italy on July 31, and his wife Hailey Bieber was there to cheer him on. "One thing I know for certain," the model wrote on Instagram alongside footage of him performing his hit song Holy in front of the crowd, "is you can't keep this guy down…" Hailey wasn't the only one excited to see Justin doing what he loves. Posting a message to his fans on Instagram, the two-time Grammy winner wrote, "Love you guys and I missed you." During his set, Justin also thanked the crowd for their love and support. "Guys, I want to say thank you so much for having me back. This is my first day back," he told the audience. "It's so good to be here. The Justice Tour is about equality. We're all the same. We know that racism is evil. But we are here to be the difference makers, thank you to every one for being a part of this tour tonight."
