Charlie Sheen gave Lindsay Lohan an early Christmas present in the form of a $100,000 check to cover the actress' huge tax bill.

Sources tell the site that Sheen and Lohan became friendly during the shooting of Scary Movie 5 in September, and Lindsay had spoken to him about her ongoing tax problems.  Sheen reportedly offered to cut her a check on the spot to help her out, but she refused.

However, last week sources close to Lohan say that the actress received a check from Sheen, and she was amazed by his generosity.

Lohan allegedly owed the IRS $233,904 in unpaid taxes for 2009 and 2010, but thanks to Sheen, that figure is now just about half of what it was.
