According to PerezHilton.com, three Los Angeles police officers were called on Saturday morning (March 14) to attend a violent argument between Lohan and Samantha Ronson in the Beachwood Canyon neighbourhood.
Neighbours had notified authorities when they heard glass shattering. Lohan, 22, and DJ Samantha Ronson, 31, refused help from the police.
The dispute comes just days after an arrest warrant was issued for Lohan for breaking probation following a 2007 drunk driving arrest. Lohan was not to drive, other than for work functions, but was recently seen driving in Las Vegas with Samantha Ronson.
