Lindsay Lohan's house was allegedly robbed by a gang of spoiled rich girls

Lindsay Lohan has accused on/off girlfriend Samantha Ronson of cheating on her. The "Mean Girls" star took to her twitter page to berate the DJ, accusing her of cavorting with two girls.

Lindsay wrote "caught" to Samantha before claiming: "Funny how I'm rushing back to see Samantha Ronson when she says she's with her step- bro alone - and 2girls? That wasn't mentioned. (sic)" 

The 23-year-old actress then laid out her plans for 2010, insisting she was going to be "true to herself" this coming year. She added: "Trust yourself, and be true to you... Don't let others distract you from who you are and what you want :) 2010 xo. (sic)"

While sending messages to her friends, she said: "I rushed back to find this lie" and "I wish I'd listened to the ones that warned me of all the cheats and lies I've spent my recent past on, rather than my career."

She then concluded: "I'm over being sad." Although Lindsay was sending direct messages to 32-year-old Samantha - the sister of super-producer Mark Ronson - she did not reply to the "Mean Girls" star.
