Actor Charlie Sheen has revealed he is “still waiting” on Lindsay Lohan to say thanks for the loan he gave her to reportedly pay an outstanding tax bill.

The two stars, who are as well known for their off-camera antics as well as their acting careers, will appear together in next year’s Scary Movie 5.

Sheen revealed to Entertainment Tonight that he gave the 26-year-old an undisclosed sum of money in lieu of a payment from a project.

He told the show: "I'm still waiting for a text to say, 'Thank you'. Anything, you know?"

Sheen added that he wishes "the best" for Lohan, and described her as a "decent young lady that is just going through a lot".

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