Lauren Conrad had a pleasant conversation with ex Derek Hough during a night out at Beacher's Madhouse in Hollywood. The designer was fairly reserved, dancing occasionally to the music. But she seemed giddy when he approached her table around midnight, giving him a huge hug hello and touching his face with her hands. Though they were friendly throughout the evening, an onlooker says, "It didn't appear like they were rekindling anything romantically."
Also at the show: Miley Cyrus, who spent her night dirty dancing with her beau Liam Hemsworth. Before she arrived, the Aussie actor started his evening enjoying some quality time at the club with brother Chris Hemsworth. And Joe Jonas took in the show with his usual posse of guy friends.
