Travis Barker and Mark Hoppus are quite close, so of course Hoppus came to Barker's wedding in Italy. After Hoppus's cancer diagnosis in 2021, Barker told E! News, "Mark is my brother and I love and support him. I will be with him every step of the way on stage and off and can't wait for us to play together again soon." Hoppus also told GQ in December 2021 that he texted Barker the same day he found out about his cancer, which ended up becoming an old-school band reunion of sorts when a few days later, both Tom DeLonge and Barker showed up at Hoppus's to talk about life. DeLonge told GQ, "And so, it wasn't some big meeting about Blink-182, it was more about brothers meeting and saying, 'How do we support Mark?'"
