Lauren Conrad wore a party hat and carried a big balloon into Trousdale club in Beverly Hills on Saturday. LC and friends, including Lo Bosworth, were there to celebrate pal Jilly Hendrix's birthday with a night on the town. The fun didn't stop there for LC, since she traveled to Las Vegas just yesterday. LC was also on the go earlier this month when she took a relaxing trip to Mexico with Frankie Delgado. The getaway was a break from LC's busy schedule, which has her juggling clothing lines and two websites. In one of her latest online posts LC gave her advice on what to wear to a wedding after having just attended a friend's nuptials.
