Everyone loves a good photo booth, including some of our favorite starlets like Lindsay Lohan, Lauren Conrad, and Audrina Patridge, who slipped into their bikinis and posed for the camera. The girls didn't quite live up to the name of the Lifestyles Make Out Booth, but they still had a great time and looked adorable at the Fourth of July DKNY Jeans Beach House party [1]. Of course Lindsay posed sultry and sexy in her red string bikini with her friend. Meanwhile The Hills [2] girls — with Justin Bobby, who caused some trouble that day [3] — went sillier with their six-picture strip. Just another reason we can't wait for the show to return Aug. 18 [4]. How fun!
