Kourtney Kardashian is Justin Bieber's new neighbour

Socialite Kourtney Kardashian and her long time partner Scott Disick have bought a house in the same neighbourhood as pop star Justin Bieber.

According to usmagazine.com, Kourtney, 34, and Scott, 30, have purchased the $5.8 million 12,000-square foot house, which is said to be a step up from their current four-bedroom home.

"They fell in love with the house," said a source.

The couple, who have two children, Mason, four, and Penelope, one, was said to be on the look out for a bigger home for the children to have more space to play in.

The four-bedroom, four-and-a-half bathroom house features a mixture of patterns, textiles and colours with no overlapping theme.
