UPDATE: Will Jane Lynch be channeling her inner Snooki? We’ve learned that the Emmy ceremony tomorrow will also feature a Jersey Shore spoof featuring the Emmy host donning a 40-lb. wig.

PREVIOUS: Some tidbits from tomorrow’s Primetime Emmy Awards are starting to get out. Sources are buzzing about Jane Lynch’s opening number and a live number by the Saturday Night Live digital video masters, the Lonely Island guys, both featuring “awesome cameos.” It is unclear whether Charlie Sheen, who is expected to appear on the show tomorrow, will take part in any of them. But the two numbers are described as highlights of the ceremony and as “epic”.  The Lonely Island Guys, Jorma Taccone, Akiva Schaffer and Andy Samberg, Emmy winners for their collaboration with Justin Timberlake Dick in a Box, were also nominated with Timberlake this year for 3-Way but lost out to another Timberlake song from the May SNL show he hosted.
