Despite the fact that the previous "Two and a Half Men" star was killed off in the fourth installment, rumor has it that "Scary Movie 5" is a reboot of the over-the-top franchise.
Lohan's had a colorful couple of months, "Scary Movie" will come off the heels of "Liz & Dick," Lifetime's Elizabeth Taylor biopic. She's next slotted to star in Bret Easton Ellis's "The Canyons."
According to TMZ, the 26-year-old reformed movie star will reportedly earn $200,000 for her brief cameo in the film, while Sheen's paycheck remains undisclosed, for now.
