In the hours before the 2011 Emmy Awards, there have been quite a few reports about what to expect during the FOX broadcast of the 63rd annual kudos.

First up, you can probably count on yet another dose of the increasingly present Charlie Sheen. Comedy Central's recent roastee is rumored to be making a cameo during the night's telecast, according to Deadline.

Sheen, who did not submit his name for his work on "Two and a Half Men" this year, is now considered likely to be a surprise presenter.

One actor who was nominated for his comedy work this past season, "30 Rock" star Alec Baldwin, will take a diminished role in the night's festivities. After initially signing on to play a TV executive in an opening, pre-taped skit, Deadline reports Baldwin pulled out after a joke poking fun at News Corp and Rupert Murdoch for the ongoing UK phone-hacking scandal was removed.

"Star Trek" vet Leonard Nimoy stepped in to play the part at the last minute.

On a significantly less dramatic note, fans of "Saturday Night Live" digital short masterminds "Lonely Island" ( Andy Samberg, Akiva Schaffer and Jorma Taccone) have something to be happy about.

THR reports a medley of their tunes will be performed live with the help of Ed Helms, Maya Rudolph and a few other guests.
