Apparently there is some drama going down with Lindsay Lohan and Samantha Ronson right now: the two reportedly have had a major fight and are holed up in Ronson's house, locking out the local police.

The police, who arrived in an attempt to serve Lohan with an arrest warrant, were unable to enter the home, as Lohan and Ronson refused to open the door. As of 4:20 EST, the police have left the home, but Lohan can be arrested at any time if she opts to leave the premises. Sources say she will remain in lockdown mode until her hearing on Monday. Yikes. [TMZ]
