Tom DeLonge and Mark Hoppus have been 'able to completely repair' their friendship

Adversity has reunited Tom DeLonge and Mark Hoppus.

The co-founders of blink-182 had a very messy falling out when DeLonge indefinitely left the seminal pop-punk band in 2015, leaving Hoppus and Travis Barker with a sour taste in their mouths. DeLonge filing for divorce in 2019 put him back in touch with Hoppus, and then Hoppus' recent cancer diagnosis helped mend their friendship.

"The way the universe works is strange because I reached out to Mark because I needed him to sign this piece of paper that had to do with my divorce," DeLonge explained to Apple Music's Zane Lowe (h/t People). "Only because of that call did I learn he had cancer. And he told me on the phone. I was like, 'Wait, what?'"

The 45-year-old Angels & Airwaves frontman continued: "We weren't really talking much at all, maybe once every couple of months, a little text here and there. But now, we talk multiple times a day. We've been able to completely repair that friendship and really cut to the depth of who we are as people and what this is all about."

On June 23, Hoppus publicly revealed he was undergoing chemotherapy to treat cancer, which he later specified is B-cell lymphoma stage 4-A.

Hoppus completed his chemotherapy three weeks ago and has been upbeat as he waits to find out whether the treatment worked:
