Charlie Sheen is allegedly helping Lindsay Lohan pay back her debts.

The former Two And A Half Men star reportedly sent the 26-year-old troubled actress a check for $100,000 to cover almost half of her hefty tax bill after they bonded while filming Scary Movie 5 together.

A source close to the Liz & Dick star told gossip website TMZ.com that she and Charlie became very close while filming the movie in September and talked about everything including her enormous debts. The 47-year-old father-of-five is said to have instantly offered to write her a check to help her out and she declined. But according to insiders, she was overjoyed when he sent the generous check directly to her business manager last week and immediately used it to pay off a huge chunk of her $233,904 tax bill.

The actress - who has been arrested six times, checked in to rehab five times and whose probation is tipped to be revoked in the near future after she allegedly lied to police officers about being behind the wheel of a car during an accident in June - is reportedly set to earn more than $2 million by the end of this year from her movies, Playboy shoot and promotional tweets.

Anger Management star Charlie - who has been in rehab five times - topped the Forbes list of highest paid actors on TV last year after making $40 million.
