Justin Bieber bought his dad a $850,000 house.

The-19-year-old star purchased a five- bedroom cabin-style home in Ontario, Canada for his father, Jeremy, half-sister Jazmyn and half-brother Jaxson to ensure they have a comfortable life.

A source told gossip website TMZ.com: ''Justin wants to make sure his half-brother and half-sister are living in a really nice home.''

The property is located in the Canadian wilderness in a small town with a population of 8,000 and the residents are sure to know who they are since the family name 'Bieber' is plastered to their mailbox.

Justin is currently living in a $6million mansion in Calabasas, Los Angeles.

The teenage heartthrob hasn't been too popular with his neighbours after reportedly been accused of driving recklessly and spitting on fellow residents in the Oaks gated community.

His mother, Pattie Mallette, has recently admitted she finds it ''difficult'' to let her famous son make his own mistakes.

She said: ''When your kids hit a certain age your parenting style changes and it is hard letting go.''
