Lohan 'rants about Ronson on Twitter'

Lindsay Lohan has apparently launched a Twitter rant about her on/off girlfriend Samantha Ronson.

The Mean Girls actress, who reportedly reunited with Ronson again in September, claimed on the social networking site that the DJ's family are trying to keep them apart.

Lohan allegedly tweeted: "@samantharonson doesn't respond 2me b/c her family will cut her off if she contacts me...They control the one I love & im incapable of making any sort of difference."

She continued: "I'm in love with her, as she is in love with me... but her loved ones-hate her brilliance & resent her happiness."
