Maybe she wants to be pregnant to avoid jail time and get some favorable press.
Don't kick someone when they're down. Lindsay Lohan needs help and steady work. Yeah sure, she needs to take responsibility for herself. But that isn't easy when there's not much of a foundation on which to build.
She has screwballs for parents so she has no support, financial or emotional. Yes, she's in her 20s, but it takes years to undo what she's been through be it self-imposed or family upheaval. Give her a break. Give her a job. Give her rehab. Whatever. But this continual trashing of Lindsay Lohan is going to kill her. Literally kill her.
