A Miami-Dade County jail official says the 35-year-old Newton was arrested Friday evening on charges of resisting police and trespassing on property after a warning. He was released Saturday evening on $2,000 bond.
Newton has had legal troubles before.
In 2010, Australian "Transformers" actress Rachael Taylor took out a restraining order against then-boyfriend Newton, accusing him of violently assaulting her while the couple were in Rome. He was dropped as host of a new Australian talent series.
In 2007, he pleaded guilty to assaulting then-girlfriend Brooke Satchwell during a breakup argument. Earlier that year, Newton spent 28 days in a Melbourne rehab clinic that specializes in drug and alcohol issues.
