Lauren Conrad was accompanied by a male friend as she stepped out of Katsuya in LA yesterday following dinner with pals. It was LC's latest evening out after also recently partying at Beacher's Madhouse, where she reportedly ran into her ex, Derek Hough. LC and Derek apparently shared a few friendly words, though it didn't look like the duo were headed for reconciliation. The couple split in November and LC's been busy with family, fashion, and philanthropy since. Over the holidays, she treated teens from the LA Children's Hospital to a shopping spree at Kohl's before heading out of town for the break. LC was back in the spotlight for New Year's Eve, which she celebrated in Las Vegas with Stephanie Pratt.
