Lindsay Lohan got an unexpected visitor in rehab. Lohan was paid a visit by fellow actor Ben Affleck. The Argo director dropped in on Lohan to guide her through her rehab and give her advice on how to reclaim her dying career.

Affleck spent time in rehab in 2001 and has clearly jumped back form his demons. Lohan has had many attempts at recovering post rehab but has found herself back in the treatments centers time and time again. Ben, hoping this rehab stint will be her last, gives the Mean Girls actress a piece of advice.

So far whatever Ben told Lindsay has been working. Lohan was a big hit hosting Chelsea Lately and has worked with Oprah Winfrey to make a docu-series documenting her time post rehab.

"I thought that she's in the best place that I've ever seen her," Winfrey told "Good Morning America" earlier this month of her sit-down interview with Lohan.

"I believe that she believes that she is now ready. And she admitted that there

were other times when she was pretending to be ready and not quite sure. And sometimes resentful that she was being, you know, put in a position where she had to go to rehab. I think this is the first time I could see it really benefited her."

So what do you think Ben told Lindsay to keep her clean?
