Say what you want about Samantha Ronson. Are they dating? Are they just friends? Who cares, right. The important thing is that whatever Sam is to Lindsay Lohan, it must be pretty special.

According to a friend, the LiLo has become a new woman and is putting her career back on track by showing up on time for shooting of her new movie Labor Pains. The friend credits Lohan’s girlfriend, Samantha Ronson who has a “calming effect on her.”

The friend says,

She’s showing up early for call time [on her new flick, ‘Labor Pains’], she knows her lines and her co-workers actually like her. She’s a total pro now.
