Former 'Two and a Half Men' actor will poke fun at himself.
The former 'Two and a Half Men' actor has been lined up for a stint on stage at this weekend's ceremony according to a report.
A source told E! News: ''Even though Charlie has cleaned up his act, he still has a sense of humor about his out-of-control days.''
Another source said: ''It's all going to be a really big party moment.''
Meanwhile her boyfriend and Twilight Saga: Breaking Dawn - Part 2 co-star Robert Pattinson will not be attending this year.
Russell Brand will host the bash.
The British comedian - who announced his divorce from Katy Perry last December - will present the June 3 ceremony at the Gibson Amphitheatre in Universal City, California, for the first time, and he insists the event will be ''more impressive'' than recent box office sensation 'Avengers Assemble'.
