The 47-year-old 'Anger Management' star has been going out of his way to help the Lohan, 26, in recent months. Besides handing her USD 100,000 to help her settle a tax bill, Sheen has also been supporting her career.
Although Lohan appreciates his generous gestures, the 'Mean Girls' star has no interest in getting advice from him, reported TMZ online.
"She would never take him as a mentor. Lindsay says she talks to Charlie from time to time... But he has no business talking about her to the media," a source said.
Lohan will reportedly play herself in the episode, which is set to air in the US next month.
Sheen also paid for a portion of the dress Lohan wore to last month's amfAR charity gala � which the actress reportedly returned in tatters.
The 'Liz & Dick' actress is said to be struggling financially and she is currently living at home with her mother in New York.
