Apparently Charlie Sheen and Lindsay Lohan have some sort of troubled-actor bond, because last week Sheen gave LiLo $100,000 to help her with her unpaid taxes, TMZ reports. The two got close while filming Scary Movie 5 in September, talking about everything including the $233,904 Linds owes the IRS, sources say. Sheen offered to help her out, but she refused; he sent the money to her business manager anyway and a grateful Lohan applied it to her bill right away. (More Lindsay Lohan stories.)
