Lohan, Ronson argue at club night

Lindsay Lohan and Samantha Ronson have reportedly had a public bust-up in a nightclub.

The Mean Girls star was caught on video asking people in the club foyer whether Ronson had left the venue, The Sun reports.

An onlooker said: "Lindsay decided she was going to surprise Sam at the club and showed up around 1am.

"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 to a security guard."

Lohan then drove off in her own car.
