She's already quit smoking (for like a week at least). Now Lindsay Lohan is out to clean house professionally as she looks to salvage her career.

No, she hasn't cut ties with her enabling parents or all of the lowlife hangers-on who are a big reason she's in her current legal mess. No way.

But she did sever her relationship with her management company. It's not all their fault that she's a train wreck, but any change can't hurt.

“She was really ready for a change and decided to leave Creative Artist Agency and join International Creative Management,” a source said.

In 2005 the star dumped Endeavor for Creative Artist Agency because she wanted more A-list projects. Instead, she got more DUI arrests.

Just kidding. Well, kind of. That wasn't CAA's doing, but in any event, she's decided now is the time for a clean break and a fresh start.

The 24-year-old has chosen one of the world’s largest talent and literary agencies and is reading scripts with plans return to work soon.

We'll see what the judge has to say about that, but good for her.
