Considering that he allegedly threatened to kill someone with a machine gun just last month, Lindsay Lohan might not want to get on Charlie Sheen's bad side!

The warlock made a generous $100,000 offering to his Scary Movie 5 co-star in order to lighten the burden of her massive tax debt.

Nothing.

What did Lindsay have to say about this? Find out after the jump!
