His long-term entertainer companion Paul Petersen - who showed up with Mickey Jr on the principal time of
'The Mickey Mouse Club' - affirmed the news on Facebook, honoring Mickey Jr's multi-gifted character.
"I initially met Mickey, the most established of nine kin sired by his well known father, when he and Timmy were employed by Disney to be Mouseketeers in 1955.
"Mickey Junior was tall and capable. He could sing, dance and act... what's more, cause problems. We three were terminated for Conduct Unbecoming a Mouse!"
