California - Lauren Bosworth, best known as "Lo" on MTV's reality show 'The Hills,' leaves new West Hollywood nightclub Mi-6, named after the British Secret Intelligence Service (a.k.a. MI6) and meant to conjure the sleek luxury of the James Bond movies, where she celebrated her 23rd birthday with friends!

Lauren Bosworth enjoyed her birthday party wearing a very sexy black dress with a nice glimmering necklace. She was also photographed holding her gifts including a bunch of flowers before riding the cab.
