Justin Bieber has bought a $6 million luxury home in California.

The 18-year-old 'Boyfriend' hitmaker has snapped up a sprawling property in Calabasas, just north of Los Angeles - where his neighbours will include Steven Spielberg and Britney Spears.

The mansion features a swimming pool and guest house, along with a huge garage in which to keep his expanding collection of luxury cars, which includes a $160,000 customized Range Rover, a Batman-themed customized Cadillac, a Ferrari and a $113,000 Fisker Karma given to him by manager Scooter Braun for his 18th birthday.

According to American website X17online.com, Justin - who is dating former Disney star Selena Gomez - plans to install a computerized system to can control blinds, lights, gadgets and even his bath tub with a remote control. He also reportedly wants a "teenage boy's bedroom" with a raft of games consoles, arcade machines and a home cinema.

The Canadian-born singer had been hunting for a house in America for sometime and was even said to be considering buying the house 'Two and a Half Men' actor Ashton Kutcher is currently renting.
