In a new interview with The Daily Beast, the rocker explained his bond with the actor while also expressing his disappointment on the scrutiny put on his friend.
"Lily-Rose is my goddaughter and I was there when [his son] Jack was born, so we go back," he shared with the publication. "Johnny is one of the nicest people that I know—to the extent where it's almost heartbreaking how kind he is to his friends, and everyone around him. I know that he was completely crucified—unjustly."
He continued, "I would stand by him on anything."
Just a few weeks ago, Amber and Johnny reached a divorce settlement out of court, just one day before the estranged pair was scheduled to appear before a judge for a hearing.
