has a message for her critics: Back off.
The much-scrutinized star, 22, is speaking out about her sobriety and her relationship with girlfriend Samantha Ronson, among other things.
"They need to stop saying we're fighting," Lohan tells E! News
regarding reports about her romance with the 31-year-old deejay.
"People telling lies about me to her and all this garbage. I'm really a good person and I have a good heart and just want to work," says Lohan. "The only reason I go to clubs is to hear Samantha spin or be normal."
The actress, who briefly had an arrest warrant
issued for her, also urges people not to believe everything they read.
"I don't drink, I don't do drugs and I don't lie," she said. "I love to act and write and be creative, and I want to help people by playing characters that can send a positive message out to whomever may need it."
The actress, who recently dished about wanting to work with Seth Rogen,
says she is trying to tune out all the chatter about her personal life and focus on her career.
"I move forward and I change. Life's too short not to. If people would just leave my personal life alone – because it's really not that interesting – then I could land a great role. But all the sicko fans and the noise is so distracting."
And the star still has many goals she wants to accomplish. "I'd like to have my own charity, do work overseas, be in Oscar-nominated films, write movies, produce movies/shows/videos, design cloths, make music, write books," she says. "It's all possible if people would just stop judging me and accusing me and making me out to be this aloof, spoiled, ungrateful and unprofessional person that I am not
and could never be."
