On December 4, Robert De Niro will host SNL for the third time, alongside musical guest Diddy-Dirty Money. He’ll be followed the next week by second-time host and How Do You Know–promoting Paul Rudd and the now-available-on-iTunes Paul McCartney. The week after that, December 18, Eminem will join previously announced host and Tron-shilling Jeff Bridges. Can SNL find something funnier for De Niro to do than have Ben Stiller stab his erect member with a hypodermic needle? Let’s wait and see! [Splitsider]
