Sheen struck up a kinship with his co-star Lindsay Lohan on Scary Movie 5, and reportedly gifted the troubled starlet with $100,000.

In speaking with ET, Sheen admitted he had indeed given Lohan an unspecified amount of money, saying only that it was payment she was owed from a project. Although he says he was happy to "pay it forward," Sheen reveals that he has yet to have received any form of gratitude from Lohan.

"I'm still waiting for a text to say 'thank you,'" laughed Sheen. "Anything, you know?"

Nevertheless he wished "the best" for Lohan, explaining that she's "a very good and decent young lady that is just going through a lot."

He added, "She just needs a little bit of time…People need to give her time to get her s**t together."
