The generous actor's stunt-double Eddie Braun is also said to have sent a cheque for $25,000 to the fund after hearing about Jasmine through his good pal.
Charlie has donated a significant amount of money to various charities recently.
The former 'Two And A Half Men' star - who reportedly sent his co-star Lindsay Lohan a cheque for $100,000 to cover almost half of her hefty tax bill after they bonded while filming 'Scary Movie 5' together - is said to have given the rest of his fee to charity.
