Elton John envisions Lady Gaga enjoying a long reign as the Queen of Pop - because she is so "amazingly polite and respectful" to her entourage and fans.
The Rocket Man first teamed up with the pop star for a performance at the Grammy Awards last year and they recently recorded a duet for his latest movie project, Gnomeo & Juliet.
The oddball stars have since become close friends, and Elton is convinced the Poker Face hit-maker will rule the charts for years to come - because the superstar is so grounded.
He says, "I love her, she's absolutely amazing. We've become friends. What I like about the Gaga most is that she's amazingly polite and respectful to everyone around her. What I loved most about John Lennon is that he was like that. He once gave my mum a lift to the airport and came to my agent's wedding."
"The Gaga is like that. But the greatest thing about her is that she manages to let everyone think they know everything about her but no one knows anything. She's a phenomenal star - definitely someone who will be taking on the old sods like me, McCartney and Rod Stewart doing big tours for years to come. Pure genius."
