VIDEO : Australia Could Stop Singer Chris Brown From Entering Country to Perform

Controversial singer Chris Brown could face yet more tour trouble in the Asia-Pacific region -- and he hasn't even arrived there yet. Two months after getting temporarily stuck in the Philippines amid a contract dispute, the R&B artist now appears in danger of being refused entry by Australia over his domestic violence record. Brown, who pleaded guilty in 2009 to assaulting Rihanna, his pop star girlfriend at the time, has four big Australian shows scheduled for December. But activists have been calling on the government to deny him a visa.
