Lindsay Lohan had a constant stream of regular visitors while in rehab at Cliffside Malibu, but RadarOnline.com has exclusively learned one unexpected visitor was actor and producer, Ben Affleck. 
 
 As reports circulated — and were denied — that Lindsay has a role in Affleck’s upcoming film Live by Night, it turns out the idea wasn’t as far fetched as it sounds. 
 
 “Ben came to visit Lindsay while she was at Cliffside to talk about the possibility of a role in his movie,” a former patient who attended rehab with Lindsay, 27, told Radar. 
 
 “Lindsay was excited about the opportunity, telling me that she was going to have dark hair in the movie and would have an Irish accent.” 
 
 According to the insider, Affleck arrived with an assistant at the Malibu treatment center late at night just a few days before Lindsay’s birthday on July 2 and stayed for about an hour.

 “A former substance abuser himself, Lindsay said he was there to check on her and see how she was doing,” the source said. 
 
 “She tried to tell me he was being flirty with her, but that’s just Lindsay’s way of embellishing because she constantly needs attention.” 
 
 And while a source close to the movie maintains that Lindsay “isn’t being considered and won’t be in the movie,” they also didn’t deny the actor’s visit to Lilo in rehab.

– Ben Affleck knows a little something about rehab, so he decided to show his support to Lindsay Lohan during her most recent stay. While she was at Cliffside Malibu, Affleck met with her secretly to give her some tips on staying sober in Hollywood—and making a successful comeback. Sources tell TMZ that Affleck also told LiLo she's talented and has the support of others in the entertainment industry, and that LiLo was moved by his words. (Some outlets reported Affleck was offering Lindsay a role in his new movie, but TMZ says that's not the case.) Meanwhile, Lohan's much-anticipated sit-down with Oprah Winfrey airs on OWN Sunday at 9pm, and previews have been trickling out. In the latest, E! reports, Lindsay tells Oprah, "I'm my own worst enemy, and I know that." This and previous promos have shown Winfrey interrogating Lohan with questions including, "Do you think you can turn it around?", "What is it that you are addicted to?", "What's going to be different this time?", and "When you get the first DUI, is that a wake-up call?" Winfrey said last week that Lohan's responses seemed "honest" and "authentic."
