Lauren, 28, was pictured before heading onto the set of Extra, hosted by former Saved By The Bell star Mario Lopez, and was wearing a gorgeous soft pink and silver mini-dress.
The reality star-turned-fashion designer teamed her pretty summer frock with a pair of heeled sandals and kept her blonde hair in loose waves.
Extra is filmed at Universal studios in Hollywood and Lauren was also snapped chatting and laughing with Mario.
Since leaving The Hills, Lauren's career has gone from strength to strength. Not only does she run a successful lifestyle website, Lauren also has her own clothing line, LC Lauren Conrad.
Meanwhile, away from work, Lauren is busy planning her forthcoming wedding to lawyer William Tell, which is rumoured to be taking place in October.
Last week, however, Lauren took some time out to meet up with her former Hills and Laguna Beach: The Real OC co-star Lo Bosworth in New York.
