Justin Timberlake has built a putting green in his house.The golf-crazy singer is so determined to lower his handicap he has converted a room in his Los Angeles mansion into a miniature green so he can practice.A source said: "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!"Justin, who plays off an impressive six handicap, is such a fan of the sport he owns his own course - the Big Creek Golf Course near Memphis and also hosts a charity Professional Golf Association (PGA) Tour event, the Justin Timberlake Shriners Hospitals for Children Open in Las Vegas.Despite his various achievements in the music and movie industries - he has starred in films including 'The Love Guru' and 'Black Snake Moan' - Justin, 27, recently revealed his proudest accomplishments relate to his sporting passion.He said: "I loved appearing on the cover of Golf Digest magazine. I'm not going to lie. I mean, I'm done. I don't have to do another magazine cover ever again."The 'SexyBack' star is so obsessed with the sport, his girlfriend Jessica Biel began taking secret lessons last year in order to see more of him.A source said: "Jessica isn't really that interested in golf, but she really wants to get better at it. It will give her more time to spend with Justin, since he plays 18 holes a couple of times a week."
