Justin Timberlake made a run for it while filming a commercial in LA on Tuesday. He's familiar with logging a few hours on set after recently working hard on The Social Network. It's his musical career, though, that's earning him the award nominations — he's up for three Grammys for his collaborative efforts over the past year. JT's known to multitask as far as his career is concerned, but one of his projects is going through an unexpected hiccup. His Mirimichi golf course, which opened in July, is set to be closed for six months due to renovations.
