Justin Bieber's childhood home is on sale for $279,000.

The 20-year-old star's grandparents Bruce and Diane Dale have listed their three-bedroom house in Ontario, Canada - where the singer spent the majority of his younger years - and are hoping their grandson's fame will help increase the price.

According to TMZ, Justin's room remains as he left it complete with wallpaper, bedding and curtains emblazoned with the blue and white colours and crest of his favourite ice hockey team, Toronto Maple Leafs.

While Justin is said to be close to his mother Pattie Mallette's parents, his other set of grandparents, George and Kathy Bieber, recently claimed he hardly ever speaks to them because fame has gone to his head.

Speaking last year, George said: ''It's like we now live on different planets. He never calls us, and now I sometimes think he doesn't care.

''It does make me sad, as right now our lives are pretty desperate.

''Justin has just got too big for his britches. He will always be my grandson, and I am and always will be so proud of him. It's just sad that he is not a bigger part of our life.''

George also insists the 'Never Say Never' hitmaker is only too happy to help Bruce and Diane.

He said: ''For them, nothing seems to be too much trouble, and he buys them new houses, cars, luxury holidays, anything they want - but for us, nothing.''
