Elton spoke with a young Australian rapper on the latest installment of Apple Music radio's Rocket Hour.
On FaceTime, he made a prediction.
''You're already huge,'' the pop veteran told The Kid LAROI. ''But I hope you realise what's gonna happen to you in 2021. You're gonna be one of the biggest artists in the whole wide world!''
Elton also explained why he liked The Kid LAROI's music so much.
''It's not just rap. Your music covers a lot of bases.''
In a tweet after the interview, the 17-year-old called their conversation ''one of the craziest moments of my life.''
