From stumping for Obama to appearing on T.I.‘s latest CD, Paper Trail, Justin Timberlake‘s pretty busy for an artist who doesn’t have any new music of his own to promote. Does that mean he’s working on the follow-up to 2006’s FutureSex/LoveSounds? “No,” the singer recently told my coworker Lindsay Soll. “I’ve gotten that question a lot lately, especially since I just played a show in Las Vegas. I love putting out records, but it’s such a task that I feel like I’ve always been the type of person to let it just come up when it comes up.” Here’s hoping J.T. comes up with something fresh and sexy soon. My booty is stiff (sorry, Usher!) and I need something to make it bounce.
