Los Angeles: Teen pop star Justin Bieber has bought a USD 6 million mansion in Calabasas, California.

The 18-year-old has splashed out on a USD 9,000 square foot property in an affluent area in the San Fernando Valley, 22 miles from Los Angeles, as reported.

He is expected to move in at the end of June and local residents are keen to welcome him to the area.

"Justin is welcomed to Calabasas and his privacy will be respected just like everyone else's," said Mayor of Calabasas, Mary Sue Maurer.

The "Baby" hitmaker had been interested in another house, a bachelor pad which Ashton Kutcher had been renting after splitting from wife Demi Moore, but Kutcher decided to act fast and buy it so he could keep it.
