Sources confirm to E! News that LiLo was indeed denied entry Friday night into the launch party hosted by girlfriend Samantha Ronson's sister, Charlotte, for her JC Penney clothing line. (Samantha also DJ'd the bash.)
But E! News has also learned the couple later reunited at an after-party in a room at the Chateau Marmont. The party drama outside Bar Marmont was just the latest battle in an ongoing feud between Lohan and the Ronson family, as well as several anti-SamRo pals, including Nicole Richie.
