Charlie Sheen Roast: Jon Lovitz, William Shatner Join the Mock Fest

Kate Walsh, Patrice O'Neal and Amy Schumer will also rib the former “Two and a Half Men” star

The list of people who'll be raking Charlie Sheen over the coals at his Comedy Central roast is complete — and it's a varied crew indeed.

Comedy Central announced Thursday that comedians Jon Lovitz, Patrice O'Neal and Amy Schumer will be taking the dais to mock the ousted "Two and a Half Men" star, along with actress Kate Walsh and former Captain Kirk William Shatner — the latter of whom has also been the subject of a Comedy Central roast. The newly announced roasters will join Anthony Jeselnik, Steve-O, Jeffrey Ross and Mike Tyson in poking fun at Sheen.

The "Comedy Central Roast of Charlie Sheen" will tape Saturday at Sony Studios in Los Angeles, and air on Sept. 19 — perhaps not coincidentally, the same night that the revamped "Two and a Half Men" makes its debut.
