While doing promo in April 2023, James opened up to Howard Stern about his relationship with Harry a bit more. The host called the singer "so special," and explained that he never felt left in the shadow hanging out with his mega-famous friend.

"I just think [Harry is] so special as a human, but actually, you don’t have any of those feelings because ... like there is someone who wants to embrace the world they’re living into the absolute best that he can and you never ever feel like that," he told the radio personality about Harry.

James called his friendship with Harry "a positive thing in [his] life."

He also chatted about going on vacation with Harry, telling the host, "When we went on this one vacation, I made this pact where I said, 'I am only going eat when you eat. I’m going work out when you work out and I’m going eat what you eat and I think it’s going have a really positive impact on me.'"

However, he quickly admitted, "[Harry] was like, 'OK…’ I lasted 36 hours and I was like, ‘No, I’m out.’ Once I’ve had a drink, I’m like, ‘I should get some fries and I’m on holiday.'"
