Don't ever say Charlie Sheen doesn t have a conscience or a heart! Mr. House Arrest himself recently cut Lindsay Lohan a check for $100,000 to cover the actress six-figure tax bill.

Supposedly Charlie and Lindsay became friends while filming Scary Movie 5 back in September.

During their friendship on and off the set, Lindsay and Charlie talked pretty openly about everything, including Lindsay s ongoing tax problems. Sources told TMZ that Charlie offered to cut her a check back then in order to get the IRS off her tail, but Lindsay refused.

Now, let s fast forward a few months. Just last week Lindsay s business manager received a check from Charlie for $100,000. What a guy!

Sources say that Lindsay was blown away by Charlie s generous support and immediately applied the money to her outstanding $200,000+ tax bill.
