Timberlake 'builds indoor golf course'

Justin Timberlake has reportedly built a golf course at his California home .

The singer, who also has a basketball court inside his Mulholland Drive mansion, converted one of his rooms into a course to be able to practice indoors at his convenience, reports Contactmusic.

A source said: "Justin loves golf and is keen to improve his skills as much as he can. Now he can sink a few balls whenever the mood takes him.

"He uses bundled blankets to fill in for sand traps and overturned couches and tables to serve as hazards. When you first see the room, it looks like a tornado has hit it, but then Justin explains that it is perfectly set up to improve his game."

It was recently reported that Timberlake will open an eco-friendly golf course in Memphis, Tennessee.
