If you thought celebrities had it easy, guess again.

Poor Justin Timberlake has been so busy performing shows and appearing in A-list movies lately, that he’s barely found the time to fit in a game of golf.

The 29-year-old, “who is obsessed with the game”, has been working so hard lately that his swing has suffered.

He said: "My game is pretty terrible. You know, it's that old thing. When the work is good, the game suffers. But you work so you can play."

The superstar launched the Justin Timberlake Shriners Hospitals for Children Open golf tournament in Las Vegas last Tuesday (October 19).

He took to the stage to perform at the closing party for the PGA charity event yesterday ( October 23), along with Christina Aguilera, Adam Garcia, Selena Gomez, Kenny G and Sir Elton John.
