Charlie Sheen gives new meaning to the phrase "friends with benefits." The actor, 47, has proven to be a very generous pal to his Scary Movie 5 co-star Lindsay Lohan.

On Wednesday, Feb. 6, mere hours before amfAR's annual New York Gala to kick off Fashion Week, the former Two and a Half Men star put in a call to celebrity stylist Phillip Bloch to ask that he dress Lohan for the glitzy event. He even offered to "go halfsies" with the Liz & Dick actress to pay for the gown.

"Never in a business like this do you see a celebrity pay for another celebrity," Bloch tells Us Weekly of Sheen, noting that the request came from the actor himself and not from an assistant. "He's very considerate."

Lohan, for her part, made good use of Bloch's fashion expertise. Stunning in a nude-and-silver beaded fringe gown by Theia and a hooded fur by Mendel, the starlet joined celebs including Woody Allen, Karlie Kloss, John Legend and fiancee Chrissy Teigen, Chloe Sevigny, and Cee Lo Green in raising $2.3 million for AIDS research.

This is not the first time the Anger Management star has offered to lend a hand (and money) to the 26-year-old drama-prone actress. Last year, he volunteered to give Lohan $100,000 to help cover her tax debt, which reportedly amounted to more than $233,000. (The actress was said to have refused the money.)

"Charlie has a long history of helping out his friends in many ways, and this is just another example of that," his rep told E! News at the time.
