It is additionally stated, "This action follows a series of gravely serious incidents, including and not limited to two unprovoked violent assaults, which (she claims) occurred on the 13th and 14th August, 2010, while Ms Taylor was in Rome."

A statement from Taylor reads, "After much consideration and struggle I have made this personal decision to send a clear public message that violence, threats, abuse and intimidation are not acceptable and should be dealt with by the full capacity of the law."

Newton was due to begin hosting Australia's "The X Factor" but pulled out on Sunday, August 22 to focus on his treatment. He previously checked into a rehab center in Melbourne in April to seek help for alcohol abuse after he was accused of trashing a hotel room in the city where he was staying with Taylor.
