According to Gossip Cop, Robert Pattinson will appear on The Tonight Show with Jay Leno on June 15th! Last year R-Patz appeared on the rival Late Night with David Letterman to promote New Moon. Personally I think it would be hilarious if he appeared on Late Night with Jimmy Fallon. The comedian and Rob could have a lot of fun with the "Bothered" sketch! Still, I think the Jay Leno interview will be pretty funny as well.
Robert Pattinson and Kristen Stewart's relationship is bond to be touched upon, however if Oprah couldn't, Jay Leno certainly won't be pushing the issue. Don't expect any new news on what's going on between these two. I'm hoping though that Rob might have some funny stories from the set of the Twilight Eclipse movie to discuss. Perhaps he'll also let us in on the inside scoop with his new movie Water for Elephants.
No matter how the interview goes, there should be no diarrhea of the mouth with Rob like there was in Kristen Stewart's most recent interview. From watching other interviews of his, it's obvious that Robert Pattinson is more charismatic and thinks on his toes better during interviews than his co-star/alleged girlfriend.
