Samantha Ronson "I'm not using Lindsay"

Samantha Ronson has hit back at those who claim that her relationship with Lindsay Lohan is a sham. The DJ, and sister of music producer Mark Ronson, insists she's not trying to cash in on the actresse's fame. "I would never use anybody, especially someone I care about. It makes me sick when people say that. If that's the type of person I am then why would Lindsay be around me," she says. "My brother's just won 3 Grammys - he has a far greater influence in the music business. If I was going to use anybody, wouldn't I use him?"
