In addition to those stars, the network also announced that comedians Patrice O'Neal and Amy Schumer will be on the roast dias. Former Guns N' Roses guitarist Slash will also be there, but it's unclear whether he will be a roaster, or just take a long nap under his giant hat.
The full roast roster also includes previously-announced Roastmaster Seth MacFarlane, Mike Tyson, Steve-O, Anthony Jeselnik and RoastMaster General Jeffrey Ross.
The roast has the potential to be a huge blockbuster for Comedy Central. The last two events, roasts of David Hasselhoff and Donald Trump, have given the network record ratings. Giving audiences a chance to enjoy two hours of public Sheen shaming seems likely to drive the ratings even higher.
Sheen seems to be taking a good-natured approach to the extravanganza. He's recorded several promos for the network, which feature him riding alternately riding a Torpedo of Truth and driving a Crazy Train.
The Comedy Central Roast of Charlie Sheen airs Mon., Sept. 19 at 10 PM ET.
