Two upcoming Justin Bieber concerts in Japan could be in jeopardy because of the star's crew members, many of which are refusing to visit the country.
Fearing radiation and cancer risk from the recent nuclear disaster, and/or another earthquake, much of the crew wants out of the May 17 and 19 shows.
Scooter Braun, Justin's manager, is not pleased about this ...
Today in Adelaide, Australia, Braun reportedly exploded at the crew, telling them all to "Man the f**k up and do the right thing by these kids."
Members of the crew fired back at Bieber's manager, saying it wasn't safe and that Avril Lavigne and Slash had canceled their Japan concerts.
Scooter said Justin did not want to disappoint ticket-holders and that the Japanese government gave the "all clear" to visit Osaka and Tokyo.
Braun noted that Maroon 5 is still on for its upcoming Japanese concerts, but for now, there's a stalemate, and the Bieber shows are in limbo.
Justin himself has yet to weigh in on the subject ...
