Maintaining their status as a constant target for paparazzi attention, Lindsay Lohan and Samantha Ronson were spotted out and about in Los Angeles yesterday (March 11). The “Mean Girls” gal and her deejay lover made their way to their car on Beachwood Avenue, both looking rather annoyed at the surrounding shutterbugs.

In related news, FOX Pop Tarts reports that earlier this week LiLo and Sam had yet another falling out after Lohan showed up in Las Vegas to surprise her sweetie at her Prive Nightclub spinning gig. Following her set, Ronson was spotted retrieving her own car from the valet and speeding off, with Lindsay hopping into another car and chasing after her, looking visibly upset.  A source told Tarts, “Everyone is urging Lindsay to leave her.  They have the worst fights almost every day but it’s always Lindsay that does the crawling.”
