London: Teen sensation Justin Bieber has splashed out USD 10.8 million on a mansion in the Hollywood Hills which he plans to share with girlfriend Selena Gomez.

The 'Baby' hitmaker, who turned 18 on last Thursday, has treated himself to the lavish five bedroom, 9,400 sq ft home overlooking Lake Hollywood, as reported.

However, the young couple can't move into the property just yet as Ashton Kutcher has been renting the palatial pad for USD 50,000 a month since his split from wife Demi Moore last year.

Along with splashing out on a new home for himself, Bieber was also surprised with a luxury 2012 Fisker Karma electric car worth USD 100,000 by his manager Scooter Braun during a recent appearance on "The Ellen DeGeneres Show".
