Christmas is coming early for all you Justin Timberlake fans. Don't forget, he'll be hosting Saturday Night Live tomorrow night. And you'll get a double dose of JT as he's the musical guest too! Is there anything this guy can't do? This is JT's second time around hosting because his last time he was freakin' so hilarious! Another reason to tune in: Jimmy Fallon is rumored to be making a special guest appearance. I'm hoping it's during the news because I miss him and think that Seth Myers is kind of annoying.
