Ronaldo Nogueira (born July 17, 1944), better known as Ronnie Von, is a Brazilian singer, businessman and TV show host.
Ronnie became known in the 1960s associated with Brazilian rock, and since 2004 presents currently between Mondays and Fridays the TV night show Todo Seu (Portuguese for "All Yours") on TV Gazeta.
Some of his greater successes include the hits Meu Bem - a Brazilian version of The Beatles' Girl - and A Praça. He quickly earned the nickname O pequeno príncipe, or Little Prince, after participating in an interview with Hebe Camargo. Ronnie started hosting his own television program in 1966, O Pequeno Mundo de Ronnie Von. Os Mutantes became a regular guest band on the show. Besides opening the door for the band, Ronnie Von also brought Gilberto Gil and Caetano Veloso to appear on the show regularly, which would be the beginnings of the Tropicália movement, even though he was never part of the movement. During this period, the press tried to create a supposed rivalry between him and Roberto Carlos.
