Oh, the drama!

Update #2: A few officers just went to the front door and knocked, but Ronson and Lohan refuse to open it!

Update #3: The cops have have made no contact with the girls. The quarreling lovers are still barricaded in the house. The paparazzi remain camped outside.

Update #4: The cops are still there - 5 officers - just issuing parking tix to the paparazzi.

The police officers said repeatedly that they are not there to serve Lindsay with papers or arrest her.

A big banging sound was heard from inside the house around 2:15 P.M., to which everyone outside started going crazy over. "It sounded like a wall being hit with something loudly," a source on the scene tells us.
