She's come a long way since her days on The Hills.
But it was just like old times last night as Lauren Conrad relived her youth with a night out with her former co-stars at swanky LA restaurant, Il Sole.
The Hills star looked impeccably polished in a floaty mini dress, tuxedo jacket, opaque tights and black stilettos at the Who What Wear event on Thursday night.
She was joined by fellow Hills stars, Stephanie Pratt and Lo Bosworth, while Whitney Port was also in attendance.
Clutching a stylish gold chain handbag, 26-year-old Lauren joined a string of a-list names including actress Jessica Alba and celeb stylist, Rachel Zoe, to help toast the launch of new style bible, Who What Wear!
Shortly after, Lauren was spotted jumping into a car and heading across town to racy LA nightclub, Voyeur.
Famed for its raunchy dancers, Voyeur is most definitely the place to be seen in LA, so Lauren clearly had no intention of laying low.
On arriving at the club, the girls were also joined by yet another Hills star, musician Frankie Delgado.
Meanwhile, the one Hills star who didn’t jump at the chance to continue the party was Whitney Port.
The 25-year-old was also at the celebrity book launch and had been spotted chatting and laughing with her old friends throughout the evening.
But when Lauren came to leave for Voyeur, Whitney was nowhere to be seen.
Instead, Whitney quietly took herself home to compile her next blog entry.
She wrote: ‘I attended the Who What Wear party at Il Sole for the launch of their new book, What to Wear Where!'
She revealed: ‘I was so lucky to be invited and seated next to Hillary, one of the co-founders of Who What Wear. I ran into Lauren there and I was so happy to see her! It was nice to catch up - with both of our busy schedules, we don't have to time to chat as often as we'd like to.'
She added: ‘We were so excited to see each other that we had to have a little Blackberry photo shoot. Lauren took these pics and I made her send them to me as soon as I got home.’
