WELLINGTON, New Zealand (AP) — Chris Brown has canceled his tour of Australia and New Zealand after Australian authorities warned him they would probably refuse his visa. Australia’s immigration department declined to say whether Brown’s visa was refused, citing privacy concerns. However, in September, it had issued Brown a “notice of intention to consider refusal,” based on his criminal conviction for assaulting Rihanna is 2009. Brown had intended to play one show in Auckland, New Zealand. Immigration officials there say Brown withdrew his visa application before they could rule on it. Brown also canceled his appearance on last night’s “Daily Show” at the last minute, but Comedy Central would not say why.
