Sir Elton John got cheeky on the deck of his yacht in the south of France yesterday, flashing his bare butt at fellow knight Sir Michael Caine as their vessels crossed paths on the French Riviera.
Elton, 65, dropped his daks in salute to his famous friend, setting off hysterics among the entourages on both boats.
It's the second time this week that Elton has flashed his old man bum at a fellow star.
Just the other day he greeted Simon Cowell in the same fashion after the music mogul teased him for having a smaller boat.
