Justin Timberlake Musical Guest on Saturday Night Live Dec 21, 2013 with Host Jimmy Fallon (VIDEO) 

"Saturday Night Live" has announced that Jimmy Fallon will be hosting on December 21st with musical guest Justin Timberlake. 

Fallon and Timberlake are good friends who have worked on countless skits together from Fallon's SNL days and now on his late night show. Even though Timberlake is just the musical guest, he will most certainly sit in on a few skits, especially since he has done specific skits with Fallon that they will be sure to bring back for the special night. 

".@jtimberlake got any ideas? December 21st SNL" Jimmy tweeted to at Justinafter the news broke.

Lady Gaga brought the seasons best ratings for SNL last week topping Miley Cyrus from earlier this season. If anyone could top those ratings, it would be Fallon and especially Timberlake as he is back on top with the release of his two new albums this year.
