The former "Two and a Half Men" actor, Charlie Sheen, has dominated headlines this year following a number of incidents, including hospitalisations, rehab and being axed from the hit TV show.
Sheen is currently locked in a custody battle with estranged wife Brooke Mueller over their twin boys, while he also has two daughters with ex-wife Denise Richards - Sam, seven, and Lola, five.
"30 Rock" star Tracy Morgan has now slammed the actor for spiralling out of control and accused him of concentrating on his My Violent Torpedo Of Truth/Death Is Not An Option tour rather than taking care of his children.
Morgan says, "Charlie Sheen ain't funny to me. I think that's a train wreck and I feel bad for his two little kids because they're the bodies being pulled out of the train wreck. What's going to happen to them? But everybody thinks it's a joke... While this a-hole is going on stage making a fool of himself his kids are going to suffer and don't even know it because this is a cycle of abuse."
