Always wacky and entertaining boxing legend Mike Tyson has joined the lineup of celebs who will be sticking it to Charlie Sheen during his Comedy Central Roast.

Sheen, and his larger-than-life pesona, will no doubt take a serious beating during the Roast on September 10th. Cocaine, prostitutes, mugshots, -nothing will be off limits.

Other celebs to roast Charlie Sheen include Steve-O from "Jackass", comedian Anthony Jeselnik, Roast legend Jeff Ross, and TMZ creator Harvey Levin.
