Lohan, 22, had paid Ronson a surprise visit at her DJ gig at exclusive Las Vegas club Prive on March 9 at around 1am, making the 30-year-old furious.
“Lindsay decided she was going to surprise Sam at the club and showed up around 1am," the Sun quoted an onlooker at the club as saying. “Sam appeared to be furious and the two started to argue in the DJ booth, before Lindsay began dancing wildly. Sam left on her own at 3am, looking grim faced, and then a panicked-looking Lindsay raced out to her car with a drink in her hand, which she handed it to a security guard," the onlooker stated.
From a video clipping, an agitated Lohan was heard shouting: “Did she leave in my car? Did she f***ing leave? Did she f***ing leave?"
Lohan"s spokeswoman was not available for comment.
