The Hills' Lauren Conrad is making the most of her summer by hitting the town on a number of dates! The 21-year-old has been linked to American Idol's Chris Richardson and Desperate Housewives' hottie Josh Henderson. But, according to insiders, if Lauren was hoping for a slam-dunk in the game of love when she recently stepped out with NBA rookie Josh McRoberts, she was sorely mistaken. While the pair was seen leaving Hollywood hotspot Les Deux on July 17 holding hands, the date was actually a dud. "She thinks he's immature," says the insider. "It was the first and last date."
