Aw! Justin Timberlake helped raise some dough for Shriners Hospitals for Children in Las Vegas by hosting weeklong pro-celeb golf tournament, capped off by a charity concert and afterparty. But JT wasn't the only shining star on stage that night: he was joined by Jonas Brothers, Rihanna, 50 Cent, Leona Lewis, Adam Levine, Lionel Richie, and Boyz II Men.

Did Justin just call up all his friends and ask them to join him in Vegas? Nope! He went old school for this event. "I actually wrote letters," he tells People. I was old fashioned. I didn't have to stalk anyone," Anything for charity…and the love of golf, of course! "I enjoy playing the game leisurely," he says. "I don't have any aspirations to take on Tiger or anything. But I'd like to see this tournament get bigger, maybe get a few more celebrities out. Next year I might call in a few favors." Hey, Justin! We'll start practicing our swing now!
