We know Justin Timberlake loves golf after buying his own course earlier this year, but this is a little much.

JT has just dumped $800,000 into converting a room in his home into an indoor golf course!

Timberlake admits his love for the sport saying: “I am a golf fanatic. My handicap is six and I play 18 holes a couple of times a week. I converted one of the bigger rooms in my house into a miniature green.”

Actually, if Jessica Biel was our boyfriend we’d figure out ways to spend as much time away from her too.
