Is Brian Johnson singing with ACDC again?

I'm curious, could you clarify if there's any truth to the rumor that Brian Johnson, the legendary lead singer of AC/DC, has rejoined the band for a new round of performances? I've heard whispers in the industry that he's back on stage, belting out those iconic tunes once more. Is this just idle speculation, or is there substance to the belief that AC/DC has reunited with their original vocalist? I'd love to hear your thoughts on this intriguing possibility.
