Josh at a night club....

Josh Hartnett and other celebrities are not camera shy when it comes to the new social network www.usbynight.com (U.S. By Night). Usbynight.com is located in Miami, and local photographers take pictures for the website at parties and clubs in South Beach and Downtown Miami. Last week it was, among others, Josh Hartnett, who kindly posed to usbynight.com's camera both Thursday and Saturday at Tommy Lee's nightclub Rok Bar at Collins Avenue.
