Lindsay Lohan sure has generous friends!

The Liz & Dick actress rocked a shimmery Theia gown to amfAR's recent New York Gala to kick off Fashion Week, and her Scary Movie 5 co-star offered to "go halfsies" on her dress, according to Us.

Lilo's stylist Phillip Bloch told the mag: "Never in a business like this do you see a celebrity pay for another celebrity. He's very considerate."

Bloch adds that Sheen personally made the phone call. What a giver!
