Teen idol Justin Bieber has made headlines for his hard-partying lifestyle and run-ins with the law in several countries, including a January 2014 arrest for allegedly racing a Lamborghini through Miami. He announced in January on his Facebook page that he wanted to leave behind his ‘arrogant and conceited’ behaviour. Bieber arrived in Sydney on Monday to attend a week-long gathering at a Hillsong pentecostal church, in an attempt to discard his hard-partying image. ‘Justin is here, like tens of thousands of others, as a delegate who is seeking to build stronger foundations into his life,’ Hillsong Church said in a statement. Music is central to Hillsong's form of worship but the Canadian singer is unlikely to perform any of Hillsong's faith-based songs, according to the church. Last year, Hillsong's conference in Sydney attracted around 20,000 followers from more than 60 countries.
