According to FemaleFirst, there was a violent argument between Lohan and Ronson, which forced the star to leave the house. The argument started on December 31 at a club in Miami. Many witnesses reported that the two women were hurling insults at each other and continued arguing as they exited the club.
Lohan and Ronson caused a lot of damage to their hotel room, and the security guards had to separate the two women.
Lohan’s rep denied that the couple had split, "There was an argument – I don’t know the details – but they left for Los Angeles together and it’s fine."
