Lindsay Lohan was restrained by security guards from getting in Bar Marmont, where Samantha Ronson was DJing at a party for her fashion designer sister, Charlotte Ronson’s “I Heart Ronson” clothing line for JCPenney last Friday. According to sources, Samantha was in a great mood after making sure Lindsay couldn’t get in the party or her house, changing all the locks over the weekend.

The next day Lindsay used her personal Twitter account to accuse Sam of cheating on her: “Being cheated on does wonders for you. Look, I’m doing this publicly because u & ur friends call[ed] people mag… so- you win, you broke my heart. Now go away. I loved you.”

This seems to be a seriously nasty breakup, however Lindsay exclusively told E!, they are just taking a break so she can focus on her career: “We are taking a brief break so I can focus on myself.” Meanwhile Samantha happily announced her single status on her MySpace: “aura in pleasanton is very pleasant.”

Lindsay is devastated but her family is there to support her, says a source: “Is she upset? Yes. Has it been a rough week? Yes. But her family’s around her and she’s just focusing on business right now.” As for Samantha Ronson’s family, they have reportedly asked for a restraining order against the Mean Girls star.
